1.5 kW质子交换膜燃料电池堆动态工况响应特性
Response features of a 1.5 kW proton exchange membrane fuel cell stack for dynamic cycle
摘要
Abstract
The performance of a homemade 1. 5 kW proton exchange membrane fuel cell (PEMFC) stack was evaluated under dynamic drive cycle, and the variation features (response) of PEMFC stack voltage, power and reaction parameters were investigated at various onboard operation modes. It is found that there is more obvious fluctuation of stack power and voltage at high current densities due to difference between single cells. The highest variation coefficient (Cv) is 4.23% for two dynamic drive cycle periods; the difference value between the maximum and the minimum cell voltage is 0. 106 V. Data analysis indicates that PEMFC stack performance could be affected by some factors such as temperature changes of reactants and cell stack, air overflow or starvation, obvious pressure drop between anode and cathode, etc. This research could not only provide a basis for measurement and analysis of durability, but also is of important significance for parameter optimization of PEMFC running onboard关键词
