Overview

IEC 62282-6-100:2010/AMD1:2012 is Amendment 1 to the IEC standard for Fuel cell technologies - Part 6-100: Micro fuel cell power systems - Safety. Published by IEC TC 105, this amendment updates safety requirements, terminology, labeling and test procedures for micro fuel cell power systems, fuel cartridges and micro fuel cell power units. The amendment clarifies hydrogen leakage measurement, introduces specific pass/fail criteria and refines leakage test flow charts and test sequences.

Key technical topics and requirements

• Updated terminology
  • Defines fuel cartridge as a removable, non‑refillable article that supplies fuel or hydrogen.
  • Revises definitions for leakage, hydrogen leakage, and impermissible hydrogen gas loss.
• Safety information and markings
  • All micro fuel cell systems, units and fuel cartridges must be accompanied by safety information (instructions and/or warnings) covering transport, use, storage, maintenance and disposal.
  • Fuel cartridges must display an appropriate signal word (CAUTION / WARNING / DANGER), the ISO 7010 general warning sign (W001) and the text: “(See accompanying Warning Information.)” if space is limited.
• Hydrogen leakage and emission limits
  • Impermissible hydrogen gas loss threshold specified: ≥ 0.0032 g/h.
  • Operational and point-leak limits: single‑point leak < 0.016 g/h; overall emissions while ON < 0.8 g/h.
• Leakage measurement and testing procedures
  • For cartridges with Class 8 (corrosive) borohydride fuels, use liquid leak detector (bubble forming) solution or water immersion for initial detection; follow with point source gas loss testing if bubbles are seen.
  • Hydrogen emission testing is defined (E.7.3.12) and point‑source detection procedures are in E.7.3.13.
  • Visual pH inspection (pH paper) is required to detect liquid fuel/by‑product leakage (fail if pH < 3.5 or > 10.5).
• Revised test flow charts
  • Figures replaced/updated for vibration, drop, compressive loading, temperature cycling, low external pressure (68 kPa and 11.6 kPa), external short‑circuit and other fault tests with explicit pass/fail decision logic.

Practical applications

• Ensures safe design, manufacture and certification of micro fuel cell power systems, consumer microgenerators and portable hydrogen‑based power modules.
• Provides test methods for type testing and for evaluating fuel cartridges (including borohydride chemistries) under mechanical, thermal and pressure stresses.
• Supports safety documentation required for transport, storage and end‑user instructions.

Who should use this standard

• Product manufacturers and designers of micro fuel cell systems and fuel cartridges
• Compliance and certification laboratories performing IEC type tests
• Product safety engineers, regulatory agencies and test houses
• OEMs integrating micro fuel cells into consumer electronics, portable devices or backup power units

Related standards

• IEC 62282-6-100 (base publication, 2010)

The concentration limits for CO and CO in this table are the mg/m equivalent of the TWA and STEL exposure
limits.
b 3
The "DEVICE – ON" emission rate limit was based on 10 m ACH, selected as the product of the reference
volume times the air changes per hour (ACH) because it covers the reasonably foreseeable environments where
micro fuel cell power systems will be used. The interior space in a small car and the minimum volume per person
on commercial aircraft is at 1 m . The minimum ACH used on passenger aircraft is 10 and the lowest ventilation
setting in cars is 10 ACH. Homes and offices may have ACH levels as low as 0,5 but the per-person volume is
over 20 m , so a product of 10 is conservative. A further factor of safety of 10 has been added for hydrogen in
this specific case.
c
The “impermissible hydrogen gas loss” criteria for non-operating micro fuel cell power systems has been chosen
based on a scenario of micro fuel cell power systems in an enclosed space with no ventilation. The space
chosen has a volume of 0,28 m , or approximately 10 cubic feet. The criterion has been prescribed so that a
hydrogen concentration of greater than 25 % LFL is not permitted to develop over a twenty-four hour (24 h)
period, if three micro fuel cell power systems are in the enclosed space.
3 3
d WHO guideline limit is 0,000 1 g/m . Background levels are 0,000 03 g/m . The emission limit cannot push the
background level above the guideline limit.
e A seated human adult has a CO emission rate of 30 g/h. The fuel cell plus human adult emission rates are
limited such that the CO concentration does not reach the WHO 8 h concentration limit of 9 g/m . In an
environment with 10 m ACH, this limits the contribution from the fuel cell to 60 g/h.
f The allowable flammable hydrogen emission level that will not support a standing flame is 3 standard ml/min,
which is equivalent to 0,016 g/h. (Proceedings of the 2001 DOE Program Review; NREL/CP-570-30535; M.R.

The "DEVICE – ON" emission rate limit was based on 10 m ACH, selected as the product of the reference
volume times the air changes per hour (ACH) because it covers the reasonably foreseeable environments where
micro fuel cell power systems will be used. The interior space in a small car and the minimum volume per person
on commercial aircraft is at 1 m . The minimum ACH used on passenger aircraft is 10 and the lowest ventilation
setting in cars is 10 ACH. Homes and offices may have ACH levels as low as 0,5 but the per-person volume is
over 20 m , so a product of 10 is conservative. A further factor of safety of 10 has been added for hydrogen in
this specific case.
c
The “impermissible hydrogen gas loss” criteria for non-operating micro fuel cell power systems has been chosen
based on a scenario of micro fuel cell power systems in an enclosed space with no ventilation. The space
chosen has a volume of 0,28 m , or approximately 10 cubic feet. The criterion has been prescribed so that a
hydrogen concentration of greater than 25 % LFL is not permitted to develop over a twenty-four hour (24 h)
period, if three micro fuel cell power systems are in the enclosed space.
3 3
d WHO guideline limit is 0,000 1 g/m . Background levels are 0,000 03 g/m . The emission limit cannot push the
background level above the guideline limit.
e A seated human adult has a CO emission rate of 30 g/h. The fuel cell plus human adult emission rates are
limited such that the CO concentration does not reach the WHO 8 h concentration limit of 9 g/m . In an
environment with 10 m ACH, this limits the contribution from the fuel cell to 60 g/h.
f The allowable flammable hydrogen emission level that will not support a standing flame is 3 standard ml/min,
which is equivalent to 0,016 g/h. (Proceedings of the 2001 DOE Program Review; NREL/CP-570-30535; M.R.

© IEC 2012
2) If bubbles are observed, hydrogen point source gas loss detection testing in
accordance with F.7.3.13 shall be performed to ensure no release of hazardous
material to the environment.
3) If point source testing is performed, the water immersion test of step 1 shall be

other equivalent means, such as a water immersion test, on all possible leak locations
of the fuel cartridge.
2) If bubbles are observed, hydrogen point source gas loss detection testing in
accordance with F.7.3.13 shall be performed to ensure no release of hazardous
materials to the environment.
3) If point source testing is performed, hydrogen leakage measurement in accordance

bubbles due to hydrogen leakage are observed, the fuel cartridge fails the hydrogen
leakage test. See Figure F.2 and Figure F.3.

b) If the fuel cartridge is of the type that is refillable by the manufacturer (automated or by
trained technicians), it shall be filled to its rated capacity prior to testing. If the fuel
cartridge is not refillable, it shall be tested in the condition in which it completed the type
test in question. The fuel cartridge shall be tested for leaks at laboratory temperature.
There shall be no leakage from any point on the fuel cartridge.
c) For micro fuel cell power systems or micro fuel cell power units with a fuel management

no bubbles due to hydrogen leakage are observed.
