FUEL CELL SEPARATOR, FUEL CELL, AND MANUFACTURING METHOD OF FUEL CELL SEPARATOR |
| 摘要 |
A fuel cell separator includes an electrically-conductive base substrate and a carbon film formed on the base substrate. The carbon film includes a first layer formed closest to the base substrate, and a second layer formed farthest from the base substrate. A diameter of carbon particles included in the first layer is 19 nm or less, and is smaller than a diameter of carbon particles included in a layer of the carbon film other than the first layer, and a diameter of the carbon particles included in the second layer is 40 nm or less. |

1. A fuel cell separator, comprising:
an electrically-conductive base substrate; and a carbon film formed on the base substrate, wherein: the carbon film includes a first layer formed closest to the base substrate, and a second layer formed farthest from the base substrate; an average diameter of carbon particles included in the first layer is 19 nm or less, and is smaller than an average diameter of carbon particles included in a layer of the carbon film other than the first layer; and an average diameter of carbon particles included in the second layer is 17 nm or more and 40 nm or less. |
