Abstract
The structured body intended for use for an anode (1) in fuel cells, includes a structure formed by macro-pores and an electrode material. The macro-pores form communicating spaces which are produced by using pore forming materials. The electrode material includes skeleton-like or net-like connected structures of particles which are connected by sintering and which form two reticular systems which interengage: a first reticular system made of ceramic material and a second reticular system which contains metals to effect an electrical conductivity. The electrode material has the properties so that, with a multiple change between oxidizing and reducing conditions, substantially no major property changes occur in the ceramic reticular system, and an oxidization or reduction of the metals occurs in the second reticular system.
