The present invention provides improved, low-cost fuel cells having reduced fuel crossover, reduced sensitivity to metal ion impurities and ability to operate under a broad range of temperatures. The invention further provides improved methods for catalyst preparation and a new integrated flow field system for use in H/Ofuel cells.

Fuel cell having fuel tank directly attached to anode allowing pump-free fuel delivery

The present invention provides a cathode and a fuel cell, 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, the cathode 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.

Fuel cell with proton conducting membrane and with improved water and fuel management

Direct oxidation fuel cell with a divided fuel tank having a movable barrier pressurized by anode effluent gas

The present invention provides an ion conducting matrix comprising: (i) 5 to 60% by volume of an inorganic powder having a good aqueous electrolyte absorption capacity; (ii) 5 to 50% by volume of a polymeric binder that is chemically compatible with an aqueous electrolyte; and (iii) 10 to 90% by volume of an aqueous electrolyte, wherein the inorganic powder comprises essentially sub-micron particles. The present invention further provides a membrane being a film made of the matrix of the invention and a composite electrode comprising 10 to 70% by volume of the matrix of the invention.

Ion conductive matrixes and their use

The present invention provides improved, low-cost fuel cells having reduced fuel crossover, reduced sensitivity to metal ion impurities and ability to operate under a broad range of temperatures.
