An electrolyte that conducts both oxygen ions and protons has the potential to enable a solid oxide fuel cell (SOFC) to operate at lower temperatures with a variety of fuels. Now a composite cathode conducting electrons, oxygen ions, and protons shows promise for high-performance SOFC at T < 600°C.

用一个双离子电池杀死两个问题

同时传导氧离子和质子的电解质具有使固体氧化物燃料电池（SOFC）能够在较低温度下与各种燃料一起运行的潜力。现在，复合阴极传导电子，氧离子和质子，显示出在T <600°C时具有高性能SOFC的希望。
