For proton‐conducting oxides to be used in fuel cell and related technologies , sintering to form dense ceramics at low temperatures and avoiding carbonation of BaCeO 3 ‐based oxides is required. A new strategy that allows densification at much reduced temperatures (see figure) and provides high total conductivity, with the additional benefit of stabilization against degradation, is reported.
