A fuel cell system which includes a fuel distribution structure that uniformly distributes vaporizing fuel to a fuel cell is provided. As the fuel travels in a flow field channel in the fuel distribution structure, it is substantially converted to a vapor by the heat of the fuel cell operation in such a manner that the resulting vapor pressure works to substantially uniformly distribute fuel evenly outwardly across substantially the entire active area of the anode aspect of one or more membrane electrode assemblies in the system, and whereby localized, uneven 'hot spots' of fuel at the anode aspects are substantially prevented. A pair of enthalpy exchanger and heat spreader assemblies include a cathode current collector element that also has a heat spreader plate that collects and redirects heat in the fuel cell system, the assembly acting to manage the heat, temperature and condensation in the fuel cell system.

Direct oxidation fuel cell system with uniform vapor delivery of fuel

Fuel feed systems capable of providing substantially consistent flow of fuel to a fuel cell and also capable of tolerating varying pressures from a reservoir (also referred to as fuel supply or fuel cell cartridge) and the fuel cell while maintaining substantially consistent control flow to the fuel cell are disclosed.
