Investigation and analysis of proton exchange membrane fuel cell dynamic response characteristics on hydrogen consumption of fuel cell vehicle

The number of working points and response speed are two essential characteristics proton exchange membrane fuel cell (PEMFC). improper setting the may reduce life PEMFC increase hydrogen consumption vehicle. This paper explores impact as well on in real-system level. In this a dynamic model system is established verified by experiments. able to reflect process under series different speed. Based proposed model, influence vehicle driving cycles analyzed summarized, for first time, open literature. results highlight that will decreases both cases with point However, reduction range trends smaller reach an optimal level considering trade-off between saving other costs, example control cost. Also, more complex cycle, have greater applications.
