小型PEMFC电源系统热设计实验研究

THERMAL DESIGN OF PORTABLE PEMFC POWER SUPPLY WITH EXPERIMENTS

通过实验研究了利用燃料电池产生的废热以强制对流传热的方式给金属氢化物储氢器加热的可行性与具体的设计方案,与目前已报道的国内外便携式PEMFC系统相比,该方案无任何附属设备,使系统保持较高的整体效率,提高了金属氢化物储氢器的放氢性能。通过正交实验和实验数据的方差分析得知该方案在保证金属氢化物储氢器持续放氢的同时,对PEMFC无明显负面影响。

An experimental study on the feasibility of metal hydride tank to be heated by the waste heat has been performed. The detail design methodology has been introduced. Compared with the portable PEMFC systems reported in literatures, this designing methodology can improve the performance of hydrogen desorption of metal hydride tank, and no peripheral component was needed in the design system. Results of orthogonal experiments and analysis of variance shown that the project can ensure the continuous supply of hydrogen and has no obvious negative effects on PEMFC operation.
