Take gasdiffusion electrode of zinc-air battery for example and add catalyst by layers, we studied the effect of changing catalyst layer location on the performance of gasdiffusion electrode.
When various manipulations disturb the thermal boundary layer inside or the condensate film and gas-vapor diffusionlayer outside, the heat transfer effect will be better or be worse off.
各种操作条件只有影响到管程的温度边界层或壳程的冷凝液膜层和气-汽扩散层，才能强化或恶化传热过程。

The gasdiffusion through the inter-particle and the product layer was the mainly factor on the reaction rate.
