Standards Development
This part of IEC 62282 covers the requirements for the electric/thermal and environmental performance test methods applied to stationary fuel cell systems with tri-generation systems expressed as combined cooling, heat and power generation (CCHP).and combined hydrogen, heat and power generation (CHHP) This document applies to fuel: gaseous fuel (natural gas, liquefied petroleum gas, hydrogen, propane, butane, etc.) or liquid fuel (kerosene, methanol, etc.) for hydrogen-fuelled fuel cell systems.
Fuel cell systems are integrated with heat-driven chillers or heat pumps, such as absorption heat pumps and chillers to produce cooling energy in addition to heating energy.
For this purpose, the following test methods under specified operating and transient conditions are considered within the scope of this document
– electric power output;
– electrical efficiency and heat recovery efficiency of cooling and heating
– environmental performance of exhaust gas emissions, noise, vibration and discharge water quality.
This standard does not cover additional auxiliary heat generators that produce thermal energy. This standard describes type tests and their test methods only. No routine tests are required or identified, and no performance targets are set in this standard
This standard is focused on fuel cell based trigeneration system(CCHP) in order to increase the utilization rate of thermal energy discharged from the fuel cell stack.
Fuel cell based trigeneration system a new usage mode compare to the conventional system. By recovering wasted heatenergy from the stacks for cooling system, CCHP enables more efficient use of lost heat energy. it is necessary to actively convert it into cold heat for summer. When an absorption heat pump or an absorption chillers is connected to a fuel cell system, high-temperature stack heat can be converted into cooling heat. As fuel cell operated data centers need cooling and heat, the tri-generation system can be effectively applied which combined fuel cell system and a absorbing refrigerator(heat pump).
