Abstract The invention relates to improvement on deflecting plate structure in fuel battery with proton exchange membrane. The deflecting plate consists of gas inlet, gas outlet and deflecting groove. The defflecting groove is composed of groove bottom and groove wall. Diffusive and convergent channels are formed by section of the deflecting groove caused from shape versatility of groove bottom and groove wall. Multi-shapes of groove bottom and groove wall including sand hill shape, ripple shape, saw-tooth shape bring varied section of deflecting groove to multiple structure that causes 15% increased generated electricity per unit area and 10% increased electricity generating efficiency.
