Abstract:Inconsistency of current density distribution in‐plane in fuel cells is a common phenomenon. This study develops a novel highly‐integrated sensor with the feature of signal in‐situ amplification for measuring in‐plane current density. First, the sensor is designed and fabricated based on the idea of in‐situ amplification of in‐plane signals before transmission. Then, the sensor accuracy is quantitatively evaluated prior to fuel cell experiments based on a single‐point calibration approach. Finally, the distrib… Show more
