摘　　要：质子交换膜燃料电池的工作性能与许多因素有关,由于氢气是抗磁性气体,氧气是顺磁性气体,通过外加磁场可以改变燃料电池的工作性能.采用永磁铁作为梯度磁场产生源,分析了梯度磁场对燃料电池的作用机理,设计了相应的实验方案,通过实验讨论了外加磁场对燃料电池的运行稳定性、极化曲线以及不同流量条件下输出功率的影响规律,以验证梯度磁场对提高燃料电池工作性能的有效性.Proton Exchange Membrane Fuel Cell （PEMFC） performance is related to many fac- tors, and magnetic field can improve fuel cell performance because oxygen is paramagnetic gas and hydrogen is diamagnetic gas. Permanent magnet is used as gradient magnetic generator, the influ- ence of magnetic field on the fuel cell is analyzed, and an experimental scheme is designed. The magnetic field effects exerted on fuel cell operation stability, polarization curves and output power under different species flowing rate are discussed to verify gradient magnetic effectiveness on the fuel cell performance enhancement.
