AI Technical Summary
Existing technologies for detecting flow field uniformity in fuel cell bipolar plates suffer from problems such as high testing costs, impact on the flow field, or significant discrepancies between test results and actual conditions.
By employing customized membrane electrodes and thin-film pressure sensors, the pressure field distribution of gas flowing through bipolar plates is monitored, and the pressure drop of each flow channel is read using a data acquisition device. The flow distribution is inferred based on the pipe flow resistance law, thus achieving low-cost flow uniformity detection.
This method enables low-cost, non-destructive detection of flow field uniformity in fuel cell bipolar plates, accurately reflecting the gas flow state, reducing testing costs, and improving detection accuracy.
