Title:
燃料電池セパレータの表面処理方法
Document Type and Number:
Japanese Patent JP4828821
Kind Code:
B2
Abstract:
To provide a surface treatment method allowing mass production, having a large hydrophilic effect, and suppressing increase of volume resistivity, in relation to a fuel cell separator of a polymer electrolyte fuel cell, and also to provide a fuel cell separator manufactured by the surface treatment method.
A surface of the separator is instantaneously hydrophilized by a combustion chemical vapor phase deposition method for spraying a gas containing a silicon compound to the separator surface while burning it and thereby forming a nano-order silicon oxide coating layer on the surface by fine particles of silicon oxide generated by the combustion.
