In order to be able improve the hydrogen utilization as much possible while ensuring performance of air-cooled open-cathode proton exchange membrane fuel cell (AO-PEMFC), AO-PEMFC with dead-ended anode (DEA) was studied in this paper. First, transient voltage model established and causes loss were analyzed. Then, effects inlet pressure, cyclic exhaust, exhaust duration on PEMFC investigated by combining experimental methods monitoring EIS measurement. The results showed that effect pressure is not positively correlated DEA also influenced load current. Cyclic can effectively reduces degradation, optimal cycle different for has little at various currents. However, a tendency increased then stabilized increase higher current density.

The current limitations of air-cooled proton exchange membrane fuel cells (AC-PEMFCs) in water and heat management remain a major obstacle to their commercialization. A 90 cm2 full-size AC-PEMFC multi-physical field-coupled numerical model was constructed; isothermal non-isothermal calculations were performed explore the effects univariate multivariate variables on cell performance, respectively. results indicate that lower temperature is beneficial increase humidity MEA, distribution uniformity at stoichiometric ratios temperatures better. correlation between density temperature, content, concentration shows performance AC-PEMFCs influenced by multiple factors. Notably, under high operation, large generation may lead local decline, especially under-channel region with drier MEA. higher ratio can enhance dissipation, improve density, power density. Optimal achieved 300, balancing mixed influence
