Scope

This Part of GB/T 27748 is the product safety standard. It applies to stationary
packaged, self-contained fuel cell power systems or fuel cell power systems
comprised of factory matched packages of integrated systems which generate
electricity through electrochemical reactions.
This Part applies to systems
- intended for electrical connection to mains direct, or with a transfer switch,
or to a standalone power distribution system;
- intended to provide AC or DC power;
- with or without the ability to recover useful heat;
- intended for operation on the following input fuels
a) natural gas and other methane rich gases derived from renewable
(biomass) or fossil fuel sources, for example, landfill gas, digester gas,
coal mine gas;
b) fuels derived from oil refining, for example, diesel, gasoline, kerosene,
liquefied petroleum gases such as propane and butane;
c) alcohols, esters, ethers, aldehydes, ketones, Fischer-Tropsch liquids and
other suitable hydrogen-rich organic compounds derived from renewable
(biomass) or fossil fuel sources, for example, methanol, ethanol, di-
methyl ether, biodiesel;
d) hydrogen, gaseous mixtures containing hydrogen gas, for example,
synthesis gas, town gas.
This Part does not cover:
- micro fuel cell power systems;
- portable fuel cell power systems;
- propulsion fuel cell power systems.
Note: For special application such as “marine auxiliary power”, additional requirements
may be given by the relevant marine ship register standard.
This Part is applicable to stationary fuel cell power systems intended for indoor
and outdoor commercial, industrial and residential use in non-hazardous
(unclassified) areas.
This standard contemplates all significant hazards, hazardous situations and
events, with the exception of those associated with environmental compatibility
(installation conditions), relevant to fuel cell power systems, when they are used
as intended and under the conditions foreseen by the manufacturer.
This standard deals with conditions that can yield hazards on the one hand to
persons, and on the other to damage outside the fuel cell system only.
Protection against damage to the fuel cell system internals is not addressed in
this standard, provided it does not lead to hazards outside the fuel cell system.
The requirements of this standard are not intended to constrain innovation.
When considering fuels, materials, designs or constructions not specifically
dealt with in this standard, these alternatives shall be evaluated as to their
ability to yield levels of safety and performance equivalent to those prescribed
by this standard.
