The decrease of active surface area in the anode caused by CO2 accumulation is reduced through treating the diffusion layer and catalyst layer with PTFE, resulting in increased DMFC performance.

通过对阳极扩散层和催化剂层的疏水处理，降低了阳极产生的CO2导致的催化活性比表面积损失，有效地提高了电池性能。

Battery efficiency, lifespan and even safety could be vastly improved, the researchers believe, by increasing the surface area of the active materials that make up the battery electrodes.
