Fuel cell fuel control system

Image Number 4 for United States Patent #4098960.

A fuel cell fuel control system is presented in which the fuel processor is isolated from the fuel cell by means of a demand valve. The fuel processor operates at an elevated pressure with the supply of fuel forming constituents being constantly monitored in proportion to the demand based on the pressure downstream of the demand valve and the temperature in the hydrogen reformer.
