Performance Analysis of High Temperature PEM Fuel Cell with Single Flow Channel Configuration
The performance of a Proton Exchange Membrane Fuel Cell (PEMFC) is greatly affected by the geometrical and operating parameters. The flow channels are used for uniform reactant distribution throughout the active area of fuel cell. This paper numerically investigates the effects of temperature change in single flow channel high temperature PEMFC. The Numerical model of single flow channel high temperature PEM fuel cell was developed and analyzed by using COMSOL Multiphysics 4.2 software package. Different operating voltages and operating temperatures were taken to optimize the performance of high temperature PEMFC. Numerical results shown that the PEMFC with an operating temperature of 453K at an operating voltage of 0.4 V gives the better performance compared with other four operating temperatures. From the numerical results performance and polarization curves were drawn and the power densities of single flow channel high temperature PEMFC with five different operating temperatures were compared with each other.
