文摘
- •
A fully coupled 2D, along-the-channel, two-phase flow, non-isothermal, CFD model is developed.
- •
More severe water flooding at the cathode than that at the anode is numerically demonstrated.
- •
Effects of electrode properties and channel geometries on fuel cell performance are studied.
- •
Thinner GDL could result in more non-uniform and more significant temperature rise at high current densities.
- •
Novel channel design featured with multi-inlets and outlets is proposed to reduce water flooding.
