A fuel cell is a device that produces electricity through redox reaction of fuels such as oxygen and hydrogen, and is a next-generation energy conversion device that is attracting attention in the fields of transportation and power generation. However, Pt/C based fuel cells, which have been studied the most, have various problems. As the reaction proceeds, there are problems such as corrosion of the carbon, loss of activity due to repeated dissolution/aggregation of the platinum, or smooth mass transfer of fuel or by-products. In this study, we will use block copolymer with a porous nickel foam electrode. By using block copolymer, a three-dimensional anisotropic metal mesh structure will be formed on the surface of a nickel foam electrode and can fabricate a fuel cell with excellent device stability and mass transfer. |
