(Phys.org)—Be it a battery or a fuel cell, efficient electrodes are the be-all and end-all of every electrochemical cell. In the journal Angewandte Chemie, a team of Korean and American scientists has now introduced a novel material for electrodes based on affordable melamine foam and carbon black. The high porosity significantly facilitates fast mass transport and a high number of catalytically active centers drastically increase the oxygen-reducing activity of cathodes for fuel cells and metal-air batteries.
