Performance evaluation of an air breathing polymer electrolyte membrane (PEM) fuel cell in harsh environments – A case study under Saudi Arabia's ambient condition

A key parameter that determines the efficiency of proton exchange membrane fuel cells is their operating conditions. Optimization various components in these pivotal improving cell performance, as performance directly related to operational conditions are subjected to. This investigation examined viability an air breathing ambient Riyadh Saudi Arabia. validated three-dimensional 5-cell stack, modelled ANSYS was utilised generate results. Furthermore, work also considered feasibility deploying a humidifier unit for hydrogen inlet, so ascertain physical behaviour PEMFC stack. It observed stack reaches its peak during summer time (June–August), and humidification improves output by 40%.
