This standard applies to small stationary fuel cell power
systems serving as a heating appliance providing both electrical power and
useful heat with or without a peak load heating device.
This standard applies to fuel cell power systems that are intended to
be permanently connected to the electrical system of the customer (end user).
Connection to the mains directly (parallel operation) is also within the
scope of this standard
NOTE: Parallel operation is subject to the permission of the local
electric power supply utility
This standard is limited to gas and liquid fuelled fuel cell power
systems that have a heat input based on net caloric value of less than or
equal to 70 kW. For some regional applications the output electric power is
limited.
SPECIFIC LIMITATIONS WILL BE GIVEN IN THE ANNEXES FOR INDIVIDUAL
COUNTRIES.
This standard applies to systems intended for operation on the
following supplied input fuels:
a) natural gas and other methane rich gases such as city
gas;
b) fuels derived from oil refining (kerosene, liquefied
petroleum gases, propane, and butane);
c) alcohols, (methanol, ethanol);
d) hydrogen
The following
points also apply:
· The heat transfer fluid (heat output) shall be water or
a mixture of water and additives to prevent corrosion and to prevent
freezing.
· The heat transfer fluid circuit
(heat output) can be designed for open or sealed operation.
· The maximum temperature of the heat
transfer fluid (heat output) shall not exceed the regional limits shown in
the regional annexes.
· The maximum pressure of the heat
transfer fluid (heat output) circuit shall not exceed the regional limits
shown in the regional annexes.
· The maximum pressure of the
domestic water circuit, if installed, shall not exceed the regional limits
shown in the regional annexes.
This standard applies to systems with either condensing or
non-condensing conditions in the exhaust gas.
Different combustion air / flue duct circuit configurations are
accommodated.
See regional annexes for regional restrictions.
This standard applies to both indoor and outdoor installations.
This standard applies to systems with or without integrated
batteries.
This standard applies to Type Testing only.
This standard specifies the requirements for construction, safety,
installation, fitness for purpose, rational use of energy, marking, and
performance measurement of these appliances
