The main problem with traditional doping methods, like Sm 3+ doping CeO 2 (SDC), was that they did not allow enough ionic conductivity. Co-doping Sm 3+ and Cu 2+, on the other hand, does not just add ...

Researchers have identified hexagonal perovskite-related oxides as materials with exceptionally high proton conductivity and thermal stability. Their unique crystal structure and large number of ...

Microbial fuel cells, as they're called, have been around for more than 100 years. They work a little like a battery, with an anode, cathode and electrolyte – but rather than drawing electricity from ...

The material’s high proton conductivity and chemical stability at temperatures of 200–500 °C can pave the way for more durable fuel cells Fuel cells offer a promising solution for clean energy by ...
