摘要
Abstract
Using the experimental platform set up with a home-made PEMFC and other related equipment, three group experiments are designed and conducted, which associated with the factors affecting output performance of PEMFC, that is the location and pressure of pulsating hydrogen as well as regulation of load voltage to investigate the relationship between output current and time in the fuel cell at constant potential mode. The experimental results indicate that pulsation boosts the output current better than the frequent purge process; it is more beneficial to apply pulsation to the anode channel outlet rather than the inlet; the output current increases with the pressure of the pulsating reactant gas; If the required load voltage is high enough, the purge process in the system with pulsation can be canceled; at a certain load voltage level, the output current and its stability may be adjusted to the optimum by means of proper pulsation parameters.关键词
