METHOD FOR PRODUCING A SEALING ARRANGEMENT FOR A FUEL CELL UNIT AND SEALING ARRANGEMENT FOR A FUEL CELL UNIT |
摘要 |
In order to provide a method of producing a sealing arrangement for a fuel cell unit by means of which there can be produced a sealing arrangement having good gas-tight properties and good electrical insulation and which exhibits long-term stability in operation of a fuel cell system, there is proposed a method of producing a sealing arrangement for a fuel cell unit which comprises the following process steps: coating a base material of a component with an oxidizable coating material; letting the coating material diffuse into the base material; oxidizing the coating material for the purposes of producing an oxide layer which has a surface resistivity of at least 1.kQ cm2 at the operating temperature of the fuel cell unit. |
