Abstract
A load management system for hydrogen-oxygen fuel cells is provided, for powering vehicles. The load management system operates such that under normal load conditions air is provided as the oxidizing agent for the hydrogen fuel. At high output conditions the air supply is enriched with additional oxygen. The system comprises means responsive to the amperage output from the fuel cell stack to activate valve means for the addition of pure oxygen into the air inlet line. There is also provided means for electrolyzing water to produce pure hydrogen and pure oxygen gas, which may be recyclable to the fuel cell.
