電気化学的反応電極、製造方法、及びその適用機器。
Document Type and Number:
Japanese Patent JP2005501177
Kind Code:
A
Abstract:
The present invention refers to methods for the manufacture of gas-diffusion electrodes to be used for water electrolysis and ozone production, as well as electrodes for fuel cells and other electrochemical devices. A portion of protons of an ion-exchange polymer is substituted in the channels of a channel-cluster structure of an ion-exchange polymer with cations of metal catalyst. This substitution is performed via the ion exchange process. Then said cations are electrochemically reduced in the form of metal particles of a catalyst on those areas of substrate where the latter is in contact with the channels of the channel-cluster structure of the ion-exchange polymer layer.
