Engineers at Yale University have developed a new miniature fuel cell that can be used as replacement batteries in cell phones and other portable electronics. The fuel cell uses hydrogen and oxygen to form water at the outlet. The device is made of a metallic glass BMGs (bulk metallic glasses).
Typically, such fuel cells using silicon and stainless steel. However, silicon is quite fragile, and the steel is subject to corrosion. Therefore, when using fuel cells have required special protective coating, the application of which increases significantly the cost of the finished product. The use of metallic glass solves these problems. Researchers from Yale University have tested a prototype of a miniature fuel cell volume of 3 cubic meters. cm
