However, the cell developed by Pennsylvania State University researchers involves using microbial electrolysis cells to produce hydrogen from "virtually limitless supplies of sea water and river water and biodegradable organic matter". Such technology has previously required an electrical input, but the researchers used the difference between river water and sea water, a process known as...
