A key parameter that determines the efficiency of proton exchange membrane fuel cells is their operating conditions. Optimization of various components in these fuel cells is pivotal in improving cell performance, as their performance is directly related to the operational conditions the cells are subjected to.

This investigation examined the viability of an air breathing fuel cell subjected to ambient conditions in Riyadh in Saudi Arabia. A validated three-dimensional air breathing 5-cell stack, modelled in ANSYS was utilised to generate the results. Furthermore, the work also considered the feasibility of deploying a humidifier unit for the hydrogen inlet, so as to ascertain the physical behaviour of the PEMFC stack. It was observed that the performance of the stack reaches its peak during the summer time (June–August), and hydrogen humidification improves output performance by 40%.

决定质子交换膜燃料电池效率的关键参数是其运行条件。这些燃料电池中各种组件的优化对于提高电池性能至关重要，因为它们的性能直接与电池所处的运行条件有关。

这项调查研究了沙特阿拉伯利雅得市受环境条件影响的空气燃料电池的可行性。在ANSYS中建模的经过验证的三维空气呼吸5单元电池堆用于生成结果。此外，该工作还考虑了为氢气入口部署加湿器单元的可行性，以确定PEMFC堆的物理性能。据观察，在夏季（6月至8月），烟囱的性能达到了顶峰，氢气加湿将输出性能提高了40％。
