摘要： An electrode for an alkali fuel cell comprises an active layer formed by a bilayer or by a stack of a plurality of bilayers. Each bilayer is composed of a catalytic layer comprising catalyst particles of nanometric size and of a porous layer comprising two opposite faces one of which is in contact with the catalytic layer. The porous layer is made from a porous composite material comprising a hydroxide ion conducting polymer matrix in which a metallic lattice is formed constituting a plurality of electronically conducting paths connecting the two opposite faces of the porous layer. Advantageously, fabrication of such an electrode is obtained by successively performing vacuum deposition of the catalyst particles and vacuum co-deposition of the hydroxide ion conducting polymer and of the metal on a free surface of a support.
