It seems its easier to extract hydrogen from pee than water.
"While astronauts are recycling urine and sipping the results in plastic cups (or wine glasses, whatever they use up there), automobile owners may be powering cars with urine in the future. According to Dr. Gerardine Botte, an Associate Professor from the Chemical and Biomolecular Engineering department at Ohio University, extracting hydrogen from urine--using electrolysis--will cost less than extracting hydrogen from water."
