Method of producing electrode for liquid fuel cell.

摘要

A method of producing an electrode useful as anode of a liquid fuel cell using methanol as fuel. The method has the steps of coating and impregnating a porous electrode body made of carbon with a noble metal such as platinum, activating the noble metal present on and in the electrode body and then depositing a base metal such as tin onto the surfaces of the electrode body coated with the activated noble metal for the purpose of maintaining the activated state of the noble metal coating. To rapidly accomplish the deposition of the base metal while the noble metal remains in the activated state, the method comprises an additional step of immersing the electrode body with the noble metal deposited thereon in a solution containing ions of the base metal precedent to the activation step. For the same purpose, it is very favorable to form through-holes in the electrode body for use in this method.
