Protonic ceramic fuel cells are promising for energy applications, but maintaining high performance with long-term stability is an issue. Here the authors use a stable yttrium-doped barium zirconate electrolyte, achieving a power output one order of magnitude higher than existing protonic ceramic fuel cells.
