Micro Fuel Cell Made from Glass Could Power Our Gadgets

Micro Fuel Cell Made from Glass Could Power Our Gadgets

Yale University researchers have developed a tiny fuel cell that could one day power our gadgets with a clean source of energy. The micro fuel cell is made of bulk metallic glasses (BMGs) instead of the traditional materials of silicon and stainless steel, which the researchers say are fragile, inefficient and expensive. This switch, they say, creates a fuel cell that is long-lasting and low cost. Yale News explains: Silicon and stainless steel are the materials typically used in micro fuel cells. But silicon is brittle and a poor electricity conductor, and stainless steel is prone to corrosion. This means they require special coatings, which drives up production costs. Fabricating metal components on the nanoscale is complex and time-consuming also. Using bulk metallic glasses solves these problems, the researchers said. BMGs are metal alloys with randomly arranged atoms ...
