Abstract
The present invention provides a lightweight fuel cell system that operates with fuel and oxidant gases at near atmospheric pressures. The fuel cell system uses a monopolar cell design where the electrode surfaces are sufficiently accessible to the gases that it is not necessary for the oxidizer and reducer gases to be compressed. The fuel cell is ideal for personal use due to its light weight, compact size and self contained operation. An added feature of the present invention is that individual fuel cells may be linked together to achieve greater voltages or currents.
