Abstract
1295862 Fuel cell system ENERGY CONVERSION Ltd 27 Jan 1970 [28 Feb 1969] 10813/69 Heading H1B In a fuel cell system which comprises a cell or cells having hydrophobic catalysed porous nickel electrodes and which uses hydrogen as the fuel and oxygen or air as the oxidant, the air or oxygen flow rate is controlled to be proportional to current being taken from the system, a temperature and water balance being achieved in accordance with the electrolyte strength. In the embodiment the current flowing in the lead from cell stack 11 to terminal V<SP>+</SP> is sensed by circuit 13 which feeds a signal to a controller circuit 14 which controls the motor of compressor 15, the output conduit 16 of which feeds oxidant air to cell stack 11. Electrolyte e.g. KOH is pumped via reservoir 17 through cell stack 11 and fan blown heat exchanger 18 in series. The mean of the input and output electrolyte temperature to and from the cell stack 11 is sensed at circuit 24 and the signal produced controls the fan on heat exchanger 18. Water is removed to a first approximation by setting the air flow rate proportional to current. The final control of water balance is achieved by sensing the electrolyte volume and thus the electrolyte strength by means of level sensor probes 27-30 in electrolyte reservoir 17. The sensors are connected to level sensing circuit 32 the output of which is fed to temperature averaging circuit 24 which controls the fan on heat exchanger 18. If too much or too little water is removed the mean electrolyte temperature is reset to a lower or higher temperature, respectively, until the electrolyte strength reaches its nominal value.
