    Abstract: An electrolysis cell system includes a compact electrolysis cell comprising gas diffusion electrodes on each side of an aqueous electrolyte retaining matrix. A portion of the hydrogen gas produced by the cell is recirculated through the gas space of the cell and has water vapor added thereto to replenish the water used by the cell. A water metering device senses the amount of current supplied to the cell and adds the appropriate amount of water to the system in precisely the amount needed according to Faraday''s law corrected to reflect water lost in the product gases leaving the system. In a preferred embodiment a separate coolant loop flows through a thermal exchange portion of the cell in a direction opposite the flow of the recirculating product gas through the cell thereby resulting in a temperature gradient across the cell which helps maintain an even concentration of electrolyte across the cell for most efficient cell operation. The subject matter of this application is related to the subject matter of a commonly assigned application titled ''''Electrolysis Cell System Including a Recirculating Product Gas Stream for Cooling the Cell'''' by E. Parenti, D. Bloomfield, P. Grevstad and D. Beal, filed on even date herewith.

    Abstract: The internal coolant system of a fuel cell power plant utilizes a soluble salt of a metal in the coolant fluid to inhibit the corrosion of those fuel cell components that corrode due to shunt currents flowing through the coolant fluid. In a preferred embodiment a soluble salt of iron is used.
