An effective discharge method for condensed water inside the GDL using pressure gradient of a PEM fuel cell

When a fuel cell vehicle is operated in low temperature right after starting up, performance drop due to flooding often occurs in the catalyst layers, gas diffusion layers (GDL), and gas channels of the fuel cell. It is not easy to remove condensed water from the catalyst layer and GDL at low temper...
