Cyanobacteria Maps Path Toward Renewable Energy Future

In the quest for renewable fuels, scientists are taking lessons from a humble bacterium that fills our oceans and covers moist surfaces the world over. While the organism captures light to make food in a process called photosynthesis, scientists have found that it simultaneously uses the energy from that captured light to produce hydrogen. While […]

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 […]

Inexpensive New Catalysts Can Be Fine-tuned

Material could replace precious metals and produce precisely controlled electrochemical reactivity. David L. Chandler, MIT News Office. Researchers at MIT and Lawrence Berkeley National Laboratory have developed a new type of catalyst that can be tuned to promote desired chemical reactions, potentially enabling the replacement of expensive and rare metals in fuel cells. The new […]
