作为一种环境友好、经济的甲醇燃料电池燃料，我们重点研究了以木本生物质为原料，不经精制而得到的粗甲醇。杂质的影响，即，乙醇、正丁醇、甲酸甲酯和二异丙醚对DMFC性能的影响。甲酸甲酯和二异丙醚对直接甲醇燃料电池的性能影响很小，而乙醇和正丁醇对直接甲醇燃料电池的性能影响很大。当燃料以及粗生物甲醇中存在多种杂质时，降解略低于单一杂质1-丁醇的降解，1-丁醇是多种杂质中最有害的组分。当使用粗生物甲醇作为DMFC燃料时，必须去除有害杂质，例如乙醇和1-丁醇，否则需要对这些杂质的氧化也具有活性的新型催化剂。
As an environmental friendly and economical methanol for the fuel of a DMFC, we focused on a crude bio-methanol from woody biomass without refining. The effects of the impurities, i.e., ethanol, 1-butanol, methyl formate and diisopropyl ether, contained in the crude bio-methanol on the DMFC performance were investigated. Methyl formate and diisopropyl ether hardly or only slightly affected the DMFC performance, while ethanol and 1-butanol caused a significant degradation in the performance. When multiple impurities are present in the fuel as well as the crude bio-methanol, the degradation was somewhat lower than that of the single impurity, 1-butanol, which was the most harmful component of the multiple impurities. When using the crude bio-methanol as a DMFC fuel, removal of the harmful impurities, such as ethanol and 1-butanol, is necessary, otherwise a novel catalyst, which is also active for the oxidation of these impurities, required.
