The authors developed a PEM fuel cell consisting of thin separators with the thickness of 0.8mm. The paper investigates the dependence of cell performance on hydrophobic characteristics of GDL, binding pressure, channel depth, temperature and water content in the working gases in a cell with thin separators. The result shows that the best performance was obtained at lower humidity condition with a GDL which has relatively lower hydrophobic characteristics. The cell temperature and humidity condition significantly affect on the flooding performance, and it was shown that the effects can be evaluated roughly by an simple analysis of water balance proposed in the paper.
