A reverse fuel cell that uses electricity to generate hydrogen and oxygen has been announced by Greenvolt Power Corp. The company sees the cell, called a RefCell, being powered from wind or photovoltaic power sources to supply a green source of hydrogen for a future hydrogen economy and claims that its reverse fuel cell requires 20 per cent less energy than a traditional water-alkali electrolysis device while being six times smaller. It can deliver hydrogen and oxygen to storage at between 6 bar and 207 bar.
The RefCell is available in three sizes, delivering 100 l/h, 2500 l/h or 10 000 l/h of hydrogen. Greenvolt envisages the units being used to provide a source of fuel for its own alkaline fuel cells as well as providing gases for laboratory, medical and scientific applications.
