Fuel cells have higher energy density than batteries and can be a major power source for mobile electronic devices. Studies show that an effective flow design can significantly increase the output density of a fuel cell. The main role of the flow path of the fuel cell is to uniformly disperse the reactants on the electrode plate and to prevent performance deterioration due to immersion. In order to investigate the characteristics of the electrode plate channel of the polymer electrolyte fuel cell, the performance evaluation of the unit cell and the unit cell simulation experiment were carried out using a 5cm × 5cm channel electrode plate simulating ginkgo leaf vein. As a result of the performance evaluation of the unit cell, the limiting current density of serpentine was 1200 mA/cm², the maximum power density was 589 W/cm², the limiting current density of ginkgo was 1158 mA/cm2 and the maximum power density was 552 W/cm². The unit cell simulation experiment results show that the fan power of serpentine is 240 mW at the normal flow rate of air (0.00003538 kg / s) and the fan power of ginkgo is 13.7 mW.
