Examination of NON-Contacting Measurement Method of POWER Generation Current inside Single Polymer Electrolyte CELL Using Simulated Annealing

Abstract

A PEFC (polymer electrolyte fuel cell) is one of desired clean energy converters and it is expected as next-generation energy from advantages of high power generation efficiency and low emissions. In order to raise the power generation efficiency of PEFC, it is necessary to monitor the generation of current inside MEA (membrane electrode assembly) in PEFC. The inspection method of detecting the non-power generation domain inside MEA using the static magnetic field around PEFC is proposed. In this paper, the estimating method of the generation current distribution inside MEA using 3D inverse problem of simulated annealing by Ampere’s law is proposed, and the effectiveness of this method is investigated by verification experiment using an actual fuel cell.
