| titleOfInvention | Preparation method of composite membrane electrode of fuel cell |
| abstract | The invention provides a preparation method of a composite membrane electrode of a fuel cell, which is characterized in that a layer of nitrogen-doped nano diamond particle film with high graphitization degree is deposited on the surface of a monocrystalline silicon substrate, strong acid is used for carrying out surface treatment on the film, the surface layer of the film is soaked in a cerium salt/lanthanide cobaltate mixed solution after filtration, the heat preservation is carried out for 24 hours after hydrothermal treatment, a precursor of a diamond-based SDC/perovskite type composite membrane electrode is obtained, and finally the composite membrane electrode is prepared through the procedures of filtration, drying, annealing and the like. According to the invention, the doped diamond is used as an electrode framework, the doped cerium oxide and the perovskite structure are compounded and then loaded on the diamond framework, and through the high thermal conductivity and the thermal stability of the diamond, the problem of poor thermal shock resistance of the traditional cerium oxide catalyst and cobaltate compounded is solved, and the defects of large internal resistance of a thin film and poor quality of the thin film caused by large difference of thermal expansion coefficients of a cerium oxide-based electrolyte and an electrode layer of the traditional perovskite structure oxide are effectively overcome. |
