PURPOSE:To prevent deterioration in battery performance due to contactness between anode and air by providing a moistened film to the anode. CONSTITUTION:A layer consisting of a conductive and porous material which can sufficiently hold electrolyte is provided on the catalyst layer of anode. As the conductive and porous material, unwoven cloth or woven close of carbon, metal wool or porous plate can be used but any kind of material can be used so long as it is conductive, porous and has resistance for chemicals so that it is not corroded by fuel or electrolyte. If such a conductive and porous layer is moistened by electrolyte, the anode is kept wet. In case the anorite is drained while the battery is not used, contact between air and anode can be avoided and thereby degradation of battery performance can be prevented. |
