Cathode surface, led to the decrease of the internal resistance increases, activity, make Germany sunshine greatly shorten the service life of battery.
阴极表面，导致内阻增大、活性下降，使德国阳光蓄电池的使用寿命大大缩短。
Some other methods for improving catalyst activity such as cathode catalyze, alloy catalyst are also reviewed in the paper. Finally, some reasonable advises are given based on these progresses.
也回顾了一些用于改善催化剂活性的其他方法，如阴极催化、合金催化剂，根据这些进展，对今后的研究方向提出了建议。
One is low methanol oxidation activity at the anode, and the other is methanol crossover from the anode to the cathode through the membrane.
二是通常使用的全氟磺酸质子交换膜的成本高且阻醇性能差。
