摘　　要：质子交换膜燃料电池中液态水含量的多少对电池性能具有十分重要的影响。考虑了质子交换膜燃料电池催化层中气液态水的影响,在假设电池内部保持等温、稳态的基础上建立了电池阴极一维气液两相流模型。运用MATLAB软件对电池内部不同的液态水饱和度、温度以及不同阴极进气压力对单电池输出电压的影响进行了仿真,得出不同条件下的电流密度和电压之间的关系曲线,将仿真结果与实验数据相比较,该结果与实验数据符合较好,可为车用燃料电池的优化与控制提供依据。The content of liquid water is very important to the Proton Exchange Membrane Fuel Cell （PEMFC） perfor-mance. Firstly,a one-dimensional liquid and gaseous water model of catalyst layer in PEMFC was set up on the basis of isothermy and steady state inside the cell. The effect of different liquid water saturation, temperatures and input gas pressures of cathode on the output voltage of PEMFC is simulated with MATLAB software. The current density-volt-age curves are plotted in different conditions. The simulation results are coincident with the experimental data. These re-sults could be helpful for the optimization and control of vehicle fuel cell.
