 技術摘要： |
A porous catalyst includes at least one noble nano-metal particle, an oxide for forming porous structures, and a carrier material for supporting the oxide and the at least one noble nano-metal particle. The porous catalyst shows a large electrochemical surface area and a highly conductive ability. Further, the noble nano-metal particles are separated on the oxides uniformly, and the oxide of the catalyst forms a porous structure to provide a large electrochemical surface area. The porous catalyst provides excellent proton/electron transfer ability and increases the reaction rate.
一種燃料電池觸媒及其製作方法。該觸媒系統由奈米金屬觸媒承載於具電子導電性之中空管狀金屬氧化物所構成。該觸媒兼具奈米管的高表面積及高導電度之特徵。由於具催化性質之奈米金屬如Pt單金屬或PtRu合金能夠均勻分散於金屬氧化物之表面，而中空管狀之載體能提供高反應表面積，容許反應中離子及電子的快速傳遞及提高原料使用效能可有效提昇電化學反應效率。基於此二特性此一觸媒展現較先前技藝更優異的燃料電池催化活性。
