ABSTRACT

A fuel cell hydrogen recirculation system improves hydrogen utilization by circulating hydrogen from the fuel cell anode outlet to the inlet. First, by analyzing the flow rate and pressure demand of fuel cell hydrogen circulation, the model of hydrogen circulation pump is determined and the demand allocation between the inducer and the hydrogen circulation pump is carried out. Based on the one-dimensional design theory of the ejector, a one-dimensional model of the ejector is established, and by fitting the flow-pressure rise curves of the ejector and the hydrogen circulating pump, the pressures, flow rates, and cycle ratios are calculated under the two arrangement schemes of series and parallel connection, and the corresponding matching strategies are formulated. By comparing the performance of the two schemes in series and parallel with the corresponding matching strategy, the arrangement scheme of the ejector and hydrogen circulation pump is determined.
