A fuel cell comprises at least two current collectors, an electrically insulating separator element and solid electrolyte. Each current collector comprises at least one transverse passage passing through it from a first surface to a second surface and the separator element comprising opposite first and second faces is arranged between the current collectors. A plurality of transverse channels pass through the separator element from the first face to the second face and the ionically conducting solid electrolyte occupies the volume bounded by the channels of the separator element and by the passages of the current collectors. The separator element is formed by a thermoplastic polymer material and hard particles are arranged in the transverse channels.

Fuel cell with current collectors integrated with the solid electrolyte and process for manufacturing such a fuel cell

A hydrogen-oxygen fuel cell including a main cell and an auxiliary cell sharing a common electrolyte and having at least one separate electrode, circuitry for measuring the humidity ratio of the electrolyte, and control and switching circuitry for operating the main and auxiliary cells in parallel on a same load or separately on two different loads.

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.
