摘　　要：设计了一种圆柱型PEM燃料电池,研究了该燃料电池在外加磁场环境下的工作性能。实验结果表明,由磁力机产生的均匀磁场和永磁铁产生的梯度磁场均能提升圆柱型PEM燃料电池的工作性能,梯度磁场对燃料电池的输出功率密度提升更大;燃料电池的阴极、阳极位置也影响其工作性能,当以内部集流板作为阳极、外部集流板作为阴极运行时,燃料电池输出功率密度更大,而且外加磁场对燃料电池的功率提升比也更大。A cylindrical PEM fuel cell is designed to verify the working performance of the cell under exerted magnetic fields. The experimental results show that both the uniform magnetic field generated by the magnet field generator and the gradient magnetic field induced by the permanent magnet improve the working performance of the cell. The gradient magnetic field, however, enhances the output power density more than the uniform magnetic field does. The positions of the anode and the cathode also exert an influence on the fuel cell＇s performance. The power density of the fuel cell increases greatly when the fuel cell adopts inside anode and outside cathode. In addition,the exerted magnetic field also increases power density of the cell.
