<P>PROBLEM TO BE SOLVED: To provide an electrode material of a dye-sensitized solar cell made of a low cost metal material. <P>SOLUTION: The electrode material of a dye-sensitized solar cell has a catalyst layer such as platinum formed on the surface of a substrate made of a ferrite system steel having a composition which contains in mass%, C:0.15% or less, Si:1.2% or less, Mn:1.2% or less, Cr:17-32%, Mo:0.8-3%, N:0.025% or less, and as required Cu:1% or less, and the rest substantially Fe, or an austenite system steel having a composition which contains C:0.15% or less, Si:4% or less, Mn:2.5% or less, Ni:3-28%, Cr:17-32%, Mo:0.8-7%, N:0.3% or less, and further as required, Cu:3.5% or less and the rest substantially Fe, or a two-phase steel with austenite and ferrite. <P>COPYRIGHT: (C)2009,JPO&INPIT |
