Abstract
A hydrogen replenishment system for providing hydrogen to a hydrogen-receiving apparatus, the system comprising(i) an electrolytic cell for providing source hydrogen;(ii) a compressor means for providing outlet hydrogen at an outlet pressure;(iii) means for feeding the source hydrogen to the compressor means;(iv) means for feeding the outlet hydrogen to the hydrogen-receiving apparatus;(v) central processing unit means for controlling the cell and the compressor; and(vi) user activation means for operably activating the central processing unit means.The invention provides a practical user interface in the treatment of data provided, computed, measured and stored, to offer a convenient, essentially self-contained, hydrogen fuel replenishment system for vehicles based on water electrolysis. The apparatus has virtually no stored hydrogen and provides pressurized hydrogen on the demand of a user. The system is preferably operative at times of off-peak electrical supply, with electricity and water being substantially the only feedstock.
