项目摘要

We have achieved development of a platinum-free, molecular fuel cell by means of a hydrogenase enzyme model as an electrode catalyst in this research project. This is the first example of construction of a fuel cell with a molecular catalyst. The hydrogenase is an enzyme that activates not only dihydrogen but also dioxygen, which corresponds to anode and cathode reactions of the fuel cell. We have modeled the function of hydrogenase and its active site structure to produce various molecular catalysts such as nickel-iron and nickel-ruthenium complexes to oxidize dihydrogen and reduce dioxygen. We have applied these molecular catalysts to anode and cathode of the fuel cell to generate power output. Although the power density from the molecular fuel cell is lower than platinum-based fuel cell at the present, we belive that this new technology developped in this project is quite promising in future.

本研究项目以氢化酶模型作为电极催化剂，实现了无铂分子燃料电池的研制。这是用分子催化剂构建燃料电池的第一个例子。氢化酶是一种既能激活双氢也能激活双氧的酶，与燃料电池的阳极和阴极反应相对应。我们模拟了氢化酶的功能及其活性位点结构，以产生各种分子催化剂，如镍-铁和镍-钌配合物，以氧化二氢和还原二氧。我们已经将这些分子催化剂应用于燃料电池的阳极和阴极，以产生功率输出。虽然目前分子燃料电池的功率密度低于铂基燃料电池，但我们相信这个项目开发的这项新技术在未来是很有前景的。
