Proton exchange membrane fuel cells (PEMFCs) are power cells that can transform the chemical energy produced during the electrochemical reaction between hydrogen and oxygen into electrical energy. While these cells could be highly promising energy solutions, most of them can only operate at limited temperature ranges, such as 80 to 90 degrees Celsius or 140 to 180 degrees Celsius.

Researchers at the Chinese Academy of Sciences, Tianjin Normal University and Tianjin University have recently designed a new type of PEMFCs that can operate across a far wider range …
