Gas appliances - Fuel cell gas heating appliances - Fuel cell gas heating appliance of nominal heat input inferior or equal to 70 kW

This European Standard applies to the construction, the safety, the functional requirements and the test methods, as well as the classification and the marking of a fuel cell gas heating appliance, which will be operated predominantly heat followed, meeting the following boundary conditions: – maximum heat load (gas input): 70 kW – maximum electrical output: 11 kW. NOTE Due to the fact, that there are national deviations on the maximum electrical output in Europe, this maximum electrical output is independent referring the number of connected phases to the public low voltage grid. – fuel: combustion gas in accordance with EN 437 – maximum heating water temperature: 95 °C (under normal operational conditions) – process pressures in the fuel cell gas appliance: – heating water: max. 6 bar – domestic hot water (if installed): max. 10 bar – device construction: According to the expositions in accordance with CEN/TR 1749, EN 483 or EN 297 (B22, B23, B32, B33, C12, C13, C32, C33, C42, C43, C52, C53, C62, C63, C82, C83) ). This European Standard applies to type testing only. This European Standard does not contain the requirements necessary for appliances for producing electrical energy without thermal energy.

Foreword
This European Standard was prepared by the CEN/CLC/JWG FCGA, “Fuel cell gas appliances”.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50465 on
2008-05-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2009-05-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2011-05-01
This European Standard has been prepared under Mandate M/349 given to CEN and CENELEC by the
European Commission and the European Free Trade Association and covers essential requirements of
EC Directive 90/396/EEC (see Annex ZZ, which is an integral part of this document).
The essential requirement of EC Directive 90/396/EEC relating to "rational use of energy" is defined by the
maximum quantity of energy recovered (thermal and electrical energy output) from the gas energy input.
This European Standard deals with a very early state of new technology. The requirements of this European
Standard are not intended to constrain innovations. When considering materials, designs or constructions not
specifically dealt with in this European Standard the alternatives shall be evaluated as to their ability to yield
levels of safety and performance equivalent to those prescribed by this European Standard. This can be done
by a risk assessment. Furthermore not all requirements could be described in detail up to now. This is valid both
for the requirements and the test procedures. This will be done in later revisions of this European Standard.
Guidance to fuel cell stacks and their performance may be found in EN 62282-2.
Due to the development of new technology other solutions than those described in this standard are possible if
these solutions provide at least an equivalent level of safety.
Matters related to quality assurance systems, tests during production, and certificates of conformity of auxiliary
devices are not dealt with in this European Standard.
