摘要：
A printed circuit board with imbedded shunt resistors was developed and implemented to obtain distributed data in real time in an all-vanadium redox flow battery. This work discusses the development and design considerations for implementing this diagnostic approach. The in-situ data from this approach can be used to assess build quality, material performance, operating conditions, flow field design and degradation. In this work, the lateral current spread and influence of electrode material properties via a split electrode configuration was observed. It was shown that current shifts away from a hydrophobic electrode.
