HYDROGEN FUEL REPLENISHMENT PROCESS AND APPARATUS

摘要

A hydrogen replenishment system for providing hydrogen to a user, said system comprising an electrolytic cell for providing source hydrogen; a compressor means for providing outlet hydrogen at an outlet pressure; means for feeding said source hydrogen to said compressor means; means for feeding said outlet hydrogen to said user; control means for activating said cell to provide said hydrogen source when said outlet pressure fall to a selected minimum value; and user activation means for operably activating said control means. The invention provides a convenient, essentially selfcontained, hydrogen fuel replenishment system for vehicles based on water electrolyser. The apparatus has virtually no stored hydrogen by provides pressurized hydrogen on the demand of a user. The apparatus is preferably operative at times of off-peak electrical supply, with electricity and water being substantially the only feedstock.
