ELECTRODE FOR OXYGEN REDUCTION AND ELECTROCHEMICAL DEVICE USING THE SAME

Title:

ELECTRODE FOR OXYGEN REDUCTION AND ELECTROCHEMICAL DEVICE USING THE SAME

Document Type and Number:

WIPO Patent Application WO/2004/091020

Kind Code:

A1

Abstract:

To effectively utilize waste matters containing yeasts remaining after the utilization of the yeasts, it has been a practice to carbonize the waste matters and thus employ, together with other carbonized materials, in adsorbents, desiccants, soil conditioners, catalysts, etc. To enlarge the industrial applicability thereof, it is needed to search for new uses. An electrode enabling electrochemical oxygen reduction can be obtained by carbonizing a yeast-containing material and loading the thus obtained particulate or powdery carbide on an electrically conductive and air permeable substrate. When located at the cross-point of an ion pathway and an oxygen pathway, this carbide makes it possible to induce electrochemical oxygen reduction under a low overvoltage (resistance) and thus provide a large electromotive force. Thus, a novel use which has not been proposed hitherto can be provided.
