摘要： A fuel cell with which in the case where an enzyme is immobilized to one or both of a cathode and an anode, sufficient buffer ability is able to be obtained even at the time of high output operation, ability inherent in the enzyme is able to be sufficiently demonstrated, and which has superior performance is provided. In a bio-fuel cell which has a structure in which a cathode 2 and an anode 1 are opposed to each other with an electrolyte layer 3 containing a buffer substance in between, and in which an enzyme is immobilized to one or both of the cathode 2 and the anode 1, a compound containing an imidazole ring is contained in the electrolyte layer 3 as a buffer substance, and one or more acids selected from the group consisting of acetic acid, phosphoric acid, and sulfuric acid are further added. As the compound containing an imidazole ring, imidazole, 1-methylimidazole, 2-methylimidazole, 4-methylimidazole, and 2-ethylimidazole or the like is used.

摘要： There is provided a carbon dioxide immobilization unit capable of easily immobilizing carbon dioxide in the form of an organic acid or a carbohydrate under a normal environment. An anode 1 and a cathode 2 both having a surface where an oxidoreductase is present are disposed to face each other with a proton conductor 3 in between. Then, when electric power is externally supplied to the carbon dioxide immobilization unit, in the anode 1, water is decomposed to produce protons, and in the cathode 2, an organic acid or a carbohydrate is produced from the protons produced in the anode 1 and carbon dioxide. At this time, while a carbon dioxide supply section 5 supplies a high concentration of carbon dioxide to the cathode 2, oxygen produced in the anode 1 and the organic acid or hydrocarbon produced in the cathode 2 are removed from a reaction system through an oxygen removal section 4 and a product recovery section 6, respectively.
摘要翻译：本发明提供一种二氧化碳固定装置，其能够在正常环境下容易地固定有机酸或碳水化合物形式的二氧化碳。具有存在氧化还原酶的表面的阳极1和阴极2通过其间的质子导体3彼此面对。然后，当向二氧化碳固定装置外部供电时，在阳极1中水分解而产生质子，在阴极2中，由阳极1产生的质子产生有机酸或碳水化合物，二氧化碳。此时，在二氧化碳供给部5向阴极2供给高浓度的二氧化碳的同时，通过除氧，从阳极1产生的氧和阴极2中产生的有机酸或碳氢化合物从反应体系中除去第4部分和产品回收部分6。
