SOLID OXIDE FUEL BATTERY AND ELECTROLYSIS DEVICE
PROBLEM TO BE SOLVED: To suppress the recombination of holes produced in a cathode with electrons on the cathode on condition that an electrolyte of a solid oxide fuel battery is a p-type semiconductor, thereby increasing the power generation efficiency.SOLUTION: A fuel battery comprises a cathode, an electrolytic film and an anode. The cathode is formed from a first proton conductor and an electron-oxide ion mixed conductor. The first proton conductor is expressed by the following chemical formula: A(BM)O(A represents a divalent metal, B represents a quadrivalent metal, M represents a trivalent metal; and 2(3-x)=2a+4b+3m, b+m=1, and x=(3-2a-b)/2). The electrolytic film is formed from a second proton conductor expressed by the following chemical formula: A'(B'M')O(A' represents a divalent metal, B' represents a quadrivalent metal, M' represents a trivalent metal; and 2(3-x')=2a'+4b'+3m', b'+m'=1, and x'=(3-2a'-b')/2) with the provision that m is equal to or less than m'.
【課題】固体酸化物燃料電池の電解質がｐ型半導体である際に、カソードで生じた正孔がカソード上で電子と再結合することを抑制し、発電効率を向上すること。【解決手段】本発明は、カソード、電解質膜、およびアノードを具備する燃料電池である。カソードは化学式Ａa（ＢbＭm）Ｏ3-x（Ａは２価の金属、Ｂは４価の金属、Ｍは３価の金属を表し、２（３−ｘ）＝２ａ＋４ｂ＋３ｍ、ｂ＋ｍ＝１、かつｘ＝（３−２ａ−ｂ）／２により表される第１プロトン伝導体および電子−酸化物イオン混合伝導体から形成される。電解質膜は、化学式Ａ’a'（Ｂ’b'Ｍ’m'）Ｏ3-x'（Ａ’は２価の金属、Ｂ’は４価の金属、Ｍ’は３価の金属を表し、２（３−ｘ’）＝２ａ’＋４ｂ’＋３ｍ’、ｂ’＋ｍ’＝１、かつｘ’＝（３−２ａ’−ｂ’）／２）により表される第２プロトン伝導体から形成される。ｍはｍ’以下である。【選択図】図１
