The authors in this paper did research on the PEM fuel cell performance influenced by the cathode flow channel change, made comparison among PEM fuel cell performances and stability of the different cathode flow channel, optimized the cathode flow channel, and thus found the best combination of the cathode and anode flow. The PEM fuel cell performance parameters were measured by the use of fuel cell test system, and the effects of the same operating parameters, the same anode flow channel and different cathode flow channel on the battery performance were compared. The results indicated that cross-finger anode / cathode flow field of cross-finger was with the best fuel cell performance, cross-finger anode / cathode serpentine flow field of fuel cell performance was followed by, cross-finger anode / cathode flow field was parallel to the minimum fuel cell performance. The best combination of anode and cathode flow channel flow was anode flow channel cross-finger, the flow field composed of the cathode flow channel cross-refers was the best combination of flow field. The conclusion is that experimental results of the PEM fuel cell flow channel are of an important reference to the optimized combination and provide a reference basis for the use and popularity.
