High-Throughput Electrocatalyst Screening Using Bipolar Electrode Arrays: A Mini Review
Electrocatalysts play a critical role in various energy conversion and storage technologies, including fuel cells, electrolyzers, and batteries. However, finding the optimal electrocatalyst for a specific reaction is a challenging and time-consuming task, as there are many possible materials and compositions to explore. Bipolar electrode (BPE) arrays are a promising technique for high-throughput screening of electrocatalysts, as they allow simultaneous testing of multiple candidates under identical conditions without external wiring. This mini-review summarizes recent advancements and current challenges in developing and applying BPE arrays for electrocatalyst screening. We discuss the design and fabrication of BPE arrays, the methods for depositing electrocatalysts on BPEs. We also highlight some examples of BPE arrays for screening electrocatalysts for various reactions, such as oxygen reduction, hydrogen evolution, and organic oxidation. We conclude with some perspectives and suggestions for future research directions in this emerging field.
