Balancing the triple conductivity of zinc-doped cathodes for proton-conducting solid oxide fuel cells

The Zn-doped BCF36 cathode boosts proton conductivity, lowers hydration energy and achieves a peak power density of 998.6 mW cm −2 at 600 °C with a polarization resistance of 0.151 Ω cm 2 for a single cell with the BCFZ10 cathode.
