Fuel cell technologies - Stationary fuel cell power systems. Performance test methods

BS EN 62282-3-2:2006 Fuel cell technologies. Stationary fuel cell power systems. Performance test methods

BS EN 62282-3-2 describes how to measure the performance of stationary fuel cell power systems for residential, commercial, agricultural and industrial applications. The following fuel cell types have been considered:

• Alkaline Fuel Cells (AFC)
• Phosphoric Acid Fuel Cells (PAFC)
• Polymer Electrolyte Fuel Cells (PEFC)
• Molten Carbonate Fuel Cells (MCFC)
• Solid Oxide Fuel Cells (SOFC).

BS EN 62282-3-2 covers operational and environmental aspects of the stationary fuel cell power systems performance. The test methods apply as follows:

– Power output under specified operating and transient conditions

– Electrical and thermal efficiency under specified operating conditions

– Environmental characteristics; for example, gas emissions, noise, etc. under specified operating and transient conditions.

Fuel cell power systems may have different subsystems depending upon types of fuel cell and applications, and they have different streams of material and energy into and out of them. The following conditions are considered in order to determine the test boundary of the fuel cell power system.

– All energy recovery systems are included within the test boundary

– Calculation of the heating value of the input fuel (such as natural gas, propane gas, and pure hydrogen gas, etc.) is based on the conditions of the fuel at the boundary of the fuel cell power system.

Coverage for Electromagnetic Compatibility (EMC) is not provided in this standard. It also does not take into account mechanical (shaft) power or mechanical energy inputs or outputs. Mechanical systems required for fuel cell operation (i.e. ventilation or microturbines or compressors) will be included inside the test boundary.
