GAS DIFFUSION ELECTRODE WITH A HYDROPHILIC COVERING LAYER, AND PROCESS FOR ITS PRODUCTION |
摘要 |
A gas diffusion electrode for the reduction of oxygen, which contains a hydrophobic electro-catalyst layer, is described. One side of this layer is covered with a hydrophilic layer which is composed of at least one transition metal or an oxide or mixed oxide of transition metals and can also contain a current collector in the form of a metal mesh to which the hydrophobic layer can be applied. For producing the gas diffusion electrode, a hydrophobic electro-catalyst layer can first be prepared from a pulverulent mixture which contains the electro-catalyst and a hydrophobic polymer, and at least one transition metal or an oxide or mixed oxide of transition metals can be applied in a finely divided form to one side of this layer and bonded to the hydrophobic electro-catalyst layer by the application of pressure. |
