本發明包括改變陶瓷材料、微結構控制與陶瓷材料的製程,並於具奈米尺寸之陶瓷粉末上鍍上一層Ni薄膜且合成一緻密陶金材料(cermet, 陶瓷與金屬之複合材料),來開發具有高質子傳輸性之高強度緻密性薄膜。本發明選用Perovskite之具有奈米尺寸陶瓷顆粒之陶瓷粉末做為基材,然而因陶瓷的flux效能較差,而Ni具有可增加氫通量與導電性等特性又較Pd來得便宜,因此本發明以無電鍍鎳的方式,於陶瓷粉末上鍍上金屬薄膜而製作出陶金材料(cermet, 陶瓷與金屬之複合材料),並於還原氣氛下燒結而製作出燃料電池中之氫氣傳輸膜。 經過適當的前處理後,透過無電鍍的方式會使得金屬薄膜可均勻覆於每一陶瓷粉末顆粒表面,因此可減少金屬原料的使用量,且金屬鎳的薄膜可增加氫氣傳輸膜之氫通量與導電性,進而提高燃料電池的效能,對於燃料電池之效能提升研發上有很大的幫助。 This invention includes changing the ceramic materials, microstructure controlling and processing of ceramic materials. In order to develop a dense, high strength, and high proton conductive solid state membrane, the nano-size ceramic powders were coated with a thin layer of Ni film and then synthesized into a dense cermet material. In parallel, the Ni coating, which is much less expensive than the Pd coating and would further improve the proton conductivity of ceramic membrane, was applied to coat a thin layer of Ni film on each nano-size ceramic particle by electro less Ni-plating and then sintered into a dense cermet membrane for using as a hydrogen transport membrane in the fuel cell. After appropriate pre-treatment, a thin layer Ni film can be uniformly coated on the surface of each nano-size ceramic particle. This not only can reduce the use of raw metallic material, but also increase the electric conductivity as well as hydrogen flux of the membrane.
