Water Pathways Make Fuel Cells More Efficient

Researchers from the Paul Scherrer Institute (PSI) have developed a coating technique in the laboratory that could raise the efficiency of fuel cells. Fuel cells generate electricity from hydrogen and oxygen. The gases are transported to the cell’s electrodes from the outside. However, on their way to the electrodes, the gases encounter liquid water that […]

Scientists Pinpoint Ideal Locations For Geothermal Energy

Iceland has been using geothermal energy to generate electricity for decades. In 2008, however, engineers discovered a reservoir of extremely hot water that has the potential to greatly expand geothermal electricity output. Now geoscientists have for the first time produced a realistic simulation of how such reservoirs are created. They predict these natural phenomena are […]

Inexpensive Water Splitter Generates Hydrogen For 200 Hours

Requiring only a single catalyst, a new water-splitting mechansim is able continuously generate hydrogen and oxygen for more than 200 hours. The device could potentially be renewable source of clean-burning hydrogen fuel. Traditional water-splitting devices consist of two electrodes submerged in a water-based electrolyte. A low-voltage current applied to the electrodes drives a catalytic reaction […]
