This part of IEC 62282 provides test methods for the electric/thermal and environmental performance of small stationary fuel cell power systems that meet the following criteria:
output: nominal electric power output of less than 10 kW;
output mode: grid-connected/independent operation or stand-alone operation with single-phase AC output or 3-phase AC output not exceeding 1 000 V, or DC output not exceeding 1 500 V;
NOTE The limit to 1 000 V comes from the definition for \'low voltage\' given in IEV 601-01-26.
operating pressure: maximum allowable working pressure of less than 0,1 MPa (gauge) for the fuel and oxidant passages;
fuel: gaseous fuel (natural gas, liquefied petroleum gas, propane, butane, hydrogen, etc.) or liquid fuel (kerosene, methanol, etc.);
oxidant: air.
This standard covers fuel cell power systems whose primary purpose is the production of electric power and whose secondary purpose may be the utilization of by-product heat. Accordingly, fuel cell power systems for which the use of heat is primary and the use of by-product electric power is secondary are outside the scope of this standard.
All systems with integrated batteries are covered by this standard. This includes systems where batteries are recharged internally or recharged from an external source.
This standard does not cover additional auxiliary heat generators that produce thermal energy.
