Scope |
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.
