AI Technical Summary
Technical Problem
Existing fuel cell bipolar plate sealing structures suffer from poor fit and micro-gaps, leading to leakage of reactant gases and ineffective sealing.
Method used
A biomimetic microstructure array, including hydrogen-side and oxygen-side electrode microstructure arrays and MEA frame microstructure arrays combined with seals, forms a hydrogen cavity and oxygen cavity sealing structure, enhancing sealing performance.
Benefits of technology
It improves the airtightness of the fuel cell, reduces the leakage rate, and enhances the sealing effect.
