FUEL CELL WITH PROTON CONDUCTING MEMBRANE AND WITH IMPROVED WATER AND FUEL MANAGEMENT

The present invention provides a cathode (18) and a fuel cell (8), which are built to prevent escape of liquids, e.g. water and fuel solution, from the cell. Thus, according to a first aspect thereof, the present invention provides a cathode suitable for use in a fuel cell having a proton conducting...

Beschreibung
Zusammenfassung:	The present invention provides a cathode (18) and a fuel cell (8), which are built to prevent escape of liquids, e.g. water and fuel solution, from the cell. Thus, according to a first aspect thereof, the present invention provides a cathode suitable for use in a fuel cell having a proton conducting membrane (17), the cathode (18) comprising a plurality of layers including a catalyst layer and a hydrophobic porous support layer, wherein at least one of said plurality of layers is a liquid water leak-proof layer, which allows gas to pass through it and prevents passage of liquid water and/or aqueous fuel solution.
