摘要：

A new technique has been developed using a magnetic loop array to measure current distribution in electrochemical cells. The main advantage of this approach is the combination of high spatial and time resolution and stack integration with an easily handled measurement carried out independently of the cell operation. A polymer electrolyte fuel cell (PEFC) of technically relevant dimensions (about 600 cm(2) electrode area) with 5 x 8 current sensors has been constructed and operated, thus confirming the feasibility of the measurement technique.
