AI Technical Summary
Technical Problem
Metal separators in hydrogen fuel cells are prone to deformation at manifold inlet/outlet holes due to inadequate gasket optimization, leading to leaks and compromised airtightness, which affects the uniform distribution of reaction gases and cooling water.
Method used
A metal separator plate design with gasket lines that surround manifold edges, support gasket lines extending towards reaction channels, and specific length and width ratios to prevent deformation and ensure airtightness, allowing uniform gas and cooling water distribution.
Benefits of technology
Prevents deformation of manifold inlet/outlet holes, ensures airtightness, and uniformly distributes reaction gas flow rates, enhancing the performance and reliability of hydrogen fuel cells.
