ABSTRACT:
Disclosed herein is a process for preparing a reaction layer of a gas permeable electrode which comprises mixing carbon powder and a hydrophobic binding agent, hot-pressing the mixture and cooling the mixture under the hot-pressing conditions or immediately after the hot-pressing. The reaction layer prepared according to the present invention possesses connected electrolyte passages and gas passages so that all the electrolyte penetrates the electrolyte passages and all the gas penetrates the gas passages, whereby excellent contact efficiency is obtained so as to achieve improved catalyst performance.
