【報(bào)告內(nèi)容簡介】
In this resarch, the evaluation method of the distribution of the power generation current inside MEA using the distribution of static magnetic field around PEFC is proposed. The generated current distribution in the MEA is calculated by inverse problem analysis using Ampere's law from the distribution of the magnetic field around the fuel cell. The evolutionary strategy method is used by this inverse problem analysis. In addition, the current distribution estimation accuracy inside the MEA has been improved by using the weighting coefficient according to the distance between the magnetic sensor and each position in the MEA.
