(V1-xWx) 2AlC metal ceramic material for bipolar plate of proton exchange membrane fuel cell and preparation method of (V1-xWx) 2AlC metal ceramic material
The invention belongs to the technical field of fuel cells, and particularly relates to a metal ceramic material for a bipolar plate of a proton exchange membrane fuel cell and a preparation method of the metal ceramic material, the metal ceramic material is a W-doped modified vanadium aluminum carbon material, and the chemical formula of the modified vanadium aluminum carbon is (V1-xWx) 2AlC. The W-doped modified vanadium-aluminum-carbon material prepared by the method has excellent performances of metal and ceramic at the same time. The ceramic material has certain ductility at normal temperature, can be mechanically processed like metal and graphite, and has good electrical conductivity and thermal conductivity and high elastic modulus at normal temperature. And meanwhile, the ceramic material has the characteristics of the ceramic material, high yield strength, high melting point, high thermal stability and excellent corrosion resistance. Moreover, the element W is doped in the V position of the vanadium-aluminum-carbon material in a solid solution manner, so that the corrosion resistance of the vanadium-aluminum-carbon block can be greatly improved, and the vanadium-aluminum-carbon block can stably work in the working environment of the PFMFC.
本发明属于燃料电池技术领域，具体涉及一种用于质子交换膜燃料电池双极板的金属陶瓷材料及其制备方法，该金属陶瓷材料为W掺杂改性的钒铝碳材料，改性钒铝碳的化学式为(V1‑xWx)2AlC。本发明制备的W掺杂改性钒铝碳材料同时具有金属和陶瓷的优良性能。该陶瓷材料在常温下具有一定的延展性，可以像金属与石墨一样进行机械加工，在常温下具有很好的导电性能和导热性能，较高的弹性模量。同时又具有陶瓷材料的特性，具有高的屈服强度和高熔点、高热稳定性和优异的抗腐蚀性。并且，钒铝碳材料在V位置固溶掺杂W元素，能够极大地提高钒铝碳块体的耐腐蚀性能，使之能在PFMFC的工作环境中能稳定工作。
