Anode material of proton ceramic fuel cell, preparation method and application of anode material in direct ammonia fuel cell
The invention relates to a proton ceramic fuel cell anode material, a preparation method and application in a direct ammonia fuel cell, and belongs to the technical field of fuel cell electrode materials. The composition molecular formula of a cathode material of the battery is BaCo0. 4Fe0. 4Zr0. 1Y0. 1O3-delta (BCFZY), the composition molecular formula of an electrolyte material is BaZr0. 1Ce0. 7Y0. 1Yb0. 1O3-delta (BZCYYb), the composition molecular formula of an anode material is Ni-Ba (Zr0. 1Ce0. 7Y0. 1Yb0. 1) 1-2xRuxFexO3-delta (Ni-BZCYYbRF), x represents the doping amount of Ru and Fe elements, x is equal to 0.03, and delta represents the oxygen vacancy content. The ammonia catalytic activity and the conductivity of the anode of the ammonia fuel cell are improved and the impedance of the material is reduced by doping a certain content of ruthenium and iron elements into the perovskite material BaZr0. 1Ce0. 7Y0. 1Yb0. 1O3-delta. Therefore, by doping Ru and Fe, the electrochemical performance of the ammonia fuel cell can be effectively improved, the practicability of the proton ceramic ammonia fuel cell is improved, and the commercialization progress of the proton ceramic ammonia fuel cell is promoted.
