摘　　要：介绍了一种以葡萄糖为燃料的碱性直接燃料电池,它不需要贵金属催化剂、酶或者微生物就能直接把化学能转换成电能。这种单室燃料电池,在碱性溶液中以甲基紫精(MV)作为电子传递体,用泡沫镍作为阳极,空气扩散电极作为阴极。利用1 mol/L葡萄糖作为燃料,在3 mol/L KOH、10 mmol/L MV条件下构建的燃料电池,其最大功率密度为0.59mW/cm2,最大开路电压为0.65 V,最大电流密度为4.16 mA/cm2。该直接葡萄糖燃料电池,构建成本低廉,但性能优于目前已报道的以酶或微生物为催化剂的葡萄糖燃料电池,因而有望推动生物燃料电池的商业化应用。A glucose-based alkaline fuel cell was introduced in this paper, which did not need noble metal catalysts, enzyme or microorganism and could convert chemical energy to electric energy directly. The methyl viologen （MV） was used in this single-chamber fuel cell as electron mediator in alkaline solutions with nickel foam as anode and a cathode with a diffusion layer. A fuel cell utilizing 1 mol/L glucose in 3 mol/L KOH and 10 mmol/L MV generates the maximum power 0.59 mW/cm2 and the maximum open circuit voltage is 0.65 V, and the maximum current density is 4.16 mA/cm2. The cost of this fuel cell is inexpensive and the performance is better than enzyme fuel cells and microbial fuel cells which have been reported. So it is expected to promote the commercialization of bio-fuel cell applications.
