Converting Energy with Glycerol and CO in a Microfluidic Fuel Cell Equipped with CuBiO/CuO Photocathode: Bypassing Bubbles Challenge of Concurrent Water Splitting.

The imperative to address CO emissions has prompted the search for alternative approaches to capture this gas with minimal energy consumption. In this context, leveraging the CO reduction reaction (CORR) as an oxidant in fuel cells has emerged as a sophisticated strategy to convert this gas into usable energy. This study introduces a hybrid microfluidic photo fuel cell (μPFC) designed for the efficient conversion of CO and glycerol into electrical energy.
