The University of Michigan – Shanghai Jiao Tong University Joint Institute (UM-SJTU JI,) Professor Qianli Chen and her collaborators are proposing a new design principle for perovskite materials with high proton conductivity for use as electrolyte materials in solid oxide fuel cells. A paper on their work is published in the journal Advanced Energy Materials.
Solid oxide fuel cells are electrochemical devices that directly converts fuels (e.g. hydrogen, natural gas) from chemical energy into electricity, with advantages of high energy conversion efficiency, cleanliness and environmental friendliness. However, the current working temperature of solid oxide fuel cells is generally high (700-1000°C), imposing strict requirements on the high-temperature durability of all component materials for the device.
When proton-conducting ceramics are used as fuel cell electrolyte…
