Abstract:

In order to fabricate a new anode that is durable against tar in biomass­gasified gas, solution impregnation method was applied. And, the anodes before and after the power generation experiments were examined with a SEM and an EDS. In addition, the tar exposure test of the anode was also conducted. By applying solution impregnation method, the anodes were impregnated with nano­scale fine nickel particles as expected. Furthermore, the power generation performance of the cells was equivalent to that of the cells fabricated by the conventional method. However after the experiments, grain growth and sintering of the fine nickel particles was observed. In addition, carbon deposition was also observed on the anode after the tar exposure test; therefore applying the solution impregnation method does not contribute to improve the durability against tar. One of the reasons is that the nickel particles size distribution on the anode after the experiments was equivalent to that on the anode fabricated by the conventional method because of grain growth and sintering. Preventing grain growth and sintering will be a next challenge.
