A bifunctional noble metal-free catalyst with a cobalt-embedded nitrogen doped graphitized carbon shell covering a nanodiamond (ND) core (Co–N–C/ND) is synthesized. The resulting Co–N–C/ND exhibits excellent catalytic activities for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in alkaline media. The average electron transfer number of ORR on the Co–N–C/ND is 3.82 between −0...
The heat generated by a proton exchange membrane fuel cell (PEMFC) is generally removed from the cell by a cooling system. Combining heat energy and electricity in a PEMFC is highly desirable to achieve higher fuel efficiency. This paper describes the design of a new power system that combines the heat energy and electricity in a miniature PEMFC to improve the overall power efficiency in an underwater...
