Abstract:
1. An electrode for an alkali fuel cell comprising at least an active layer, conducting electrons and hydroxide ions and being catalytic, wherein the active layer is formed by a bilayer or by a stack of a plurality of bilayers, each bilayer being composed of: a catalytic layer consisting of catalyst particles of nanometric size, wherein the catalyst particles are in contact with both a hydroxide ion conducting polymer matrix and a metallic lattice, thereby forming triple points where the electrochemical reaction or reactions take place; and a porous layer comprising two opposite faces one of which is in contact with the catalytic layer, the porous layer being formed by a porous composite material comprising the hydroxide ion conducting polymer matrix in which the metallic lattice constituting a plurality of electronically conducting paths connecting the two opposite faces of the porous layer is formed.
