Evaluation of 5 kW proton exchange membrane fuel cell stack operated at 95 °C under ambient pressure

► PEMFC based on short side chain perfluoronated ionomer composite membranes are prepared. ► Cell voltage at 800 mA cm−2 of PEMFC reaches 0.61 V at 95 °C under 40% RH and ambient pressure. ► The temperature of inlet gases affects the stack performance.
