FIELD: fuel elements with solid proton-conducting membrane.
SUBSTANCE: novelty is that cathode suited for use in fuel element incorporating proton-conducting membrane has plurality of layers including catalytic layer and porous-carrier water-repelling layer; at least one of mentioned plurality of layers is water-tight and can pass gas but prevents passage of water in liquid phase and/or aqueous solution of fuel.
EFFECT: ability of preventing water and fuel solution leakage from fuel element.
