1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

FUEL CELL TECHNOLOGIES –
Part 6-300: Micro fuel cell power systems –
Fuel cartridge interchangeability

1 Scope
This part of IEC 62282 covers interchangeability of micro fuel cell (MFC) fuel cartridges to
provide the cartridge compatibility for a variety of MFC power units while maintaining the
safety and performance of MFC power systems. For this purpose, the standard covers fuel
cartridges and their connector designs. Fuel type, fuel concentration and fuel quality are also
covered. This standard also provides for the means to avoid the miss-connection of an
improper fuel cartridge. Test methods for verifying the compliance with the interchangeability
requirements for fuel and fuel cartridges are also provided in this standard.
IEC 62282-6-100 and IEC 62282-6-200 do not cover fuel cartridge or fuel from the cartridge.
IEC 62282-6-300 describes the performance test methods of fuel cartridges, the fuel from the
cartridge, and markings to realize the interchangeability of fuel cartridges. These include
performance effect of fuel cartridges, such as fuel quality which may affect the performance of
MFC power units and usable fuel volume from fuel cartridges.
A MFC power system block diagram is shown in Figure 1. MFC power systems and MFC
power units are defined as those wearable or easily carried by hand, providing d.c. outputs
that do not exceed 60 V and power outputs that do not exceed 240 VA. This standard covers
the fuel cartridge for MFC power units and the mechanical interface of connectors between
fuel cartridges and MFC power units. The main body of this standard includes methanol liquid
fuel cartridges, including methanol and water solution. Annex A shows the background used
to determine the forces expected in normal operation and in foreseeable misuse. Annex B
shows the example design for test fixtures for the fuel connector and fuel cartridge type tests.
NOTE Liquid fuel means fuel transported from a cartridge to a MFC power unit in the liquid state, and gas fuel
means fuel transported from a cartridge to a power unit in the gaseous state.

4.1.2 Safety of connectors during connecting, fueling and removing
4.1.2.1 General
No leakage and no fuel vapour loss shall occur at fuel connectors in the process of
connecting, fueling and removing of cartridge. Requirements listed under 4.1.2.2 through
4.1.2.5 shall be applied to all fuel cartridge types.
4.1.2.2 Connecting
The cartridge side connector shall have an orientation feature(s) and/or mechanical feature(s)
to ensure that the cartridge can only be connected in the proper orientation and that a wrong
cartridge is prevented from being connected to the MFC power unit. These features ensure
that the following conditions are met:
a) Improper connection of the cartridge by the user to the MFC power unit shall not damage
the cartridge side connector or MFC power unit side connector in any way that will result
in leakage or fuel vapour loss when they are subsequently connected together properly,
when the cartridge is subsequently connected properly to another MFC power unit, or
when the MFC power unit is subsequently connected properly to another fuel cartridge.
b) Attempting to connect the cartridge to a wrong MFC power unit shall not damage the
cartridge side connector or MFC power unit side connector in any way that will result in
leakage or fuel vapour loss when a correct cartridge is subsequently connected properly
to the MFC power unit or when the cartridge is subsequently connected properly to a
correct MFC unit.
c) Attempting to connect the cartridge to the MFC power unit with a force expected in normal
operation or foreseeable misuse shall not result in leakage or fuel vapour loss, or
otherwise result in subsequent leakage or fuel vapour loss if used properly in the future.
4.1.2.3 Fueling
If a force, expected under conditions of normal operation or foreseeable misuse, is applied to
the cartridge and/or MFC power unit while the cartridge is connected to the MFC power unit,
there shall be no leakage and no fuel vapour loss
