Development of the 30 kW proton-exchange membrane fuel cell stack with high power density

The 30 kW protonexchange membrane fuel cell (PEMFC) stack with high power density was successfully developed. The RD work includes four parts:(1)the construction of PEMFC working station for testing and improving the performance of single PEMFC or PEMFC stacks with power capacity ranged from 01 kW to 50 kW;(2) the engineering design of PEMFC stack with high power density; (3) assembling single PEMFCs and establishing the technologies for testing and improving the membrane electrode assemble (MEA);(4) assembling a 30 kW PEMFC stack with the power density and specific power of 720 W/L and 708 W/kg respectively and establishing the technology to test and improve the performance of PEMFC stack.
