METHOD FOR PRODUCING SEPARATOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240117482 titled 'METHOD FOR PRODUCING SEPARATOR

Simplified Explanation

The method described in the patent application involves producing a separator for fuel cells by press-forming a metal substrate into a separator shape, washing the substrate with an acid, and forming an electroconductive film on the acid-washed substrate by physical vapor deposition. During the acid washing process, at least one surface of the substrate is dissolved in a specific thickness range.

• Press-forming metal substrate into separator shape
• Washing substrate with acid
• Forming electroconductive film on acid-washed substrate by physical vapor deposition
• Acid washing dissolves substrate surface in specific thickness range

Potential Applications
