Abstract
A method for preparing a flexible membrane-free and wire-shaped fuel cell is provided. A carbon nanotube sheet is twisted and loaded with a catalyst to obtain a (CNT)@Fe3[Co(CN)6]2 cathode electrode; the carbon nanotube sheet is twisted and coated with a nickel powder to obtain a CNT@nickel particle anode electrode; and the (CNT)@Fe[Co(CN)6]2 cathode electrode, the CNT@nickel particle anode electrode, and a fuel electrolyte of H2O2 are integrated in a silicone tube to obtain a flexible membrane-free and wire-shaped fuel cell. The flexible membrane-free and wire-shaped fuel cell of the present invention can generate an open-circuit voltage of 0.88 V, while having very good flexibility, and can be woven into textiles such as clothes, thereby having great application prospects in the field of portable energy supply.
