Overview of Direct Liquid Oxidation Fuel Cells and its Application as Micro-Fuel Cells

Direct liquid fuel cells (DLFCs) are a special type of FCs that generate power output through the electro-oxidation of liquid fuels easier to handle and store than the hydrogen gas used in traditional FCs, thus increasing the range of possible applications. As electronic devices continue to evolve at the macroscale (mobile phones, laptops) and at the micro-scale (micro-electromechanical systems, wearables, and implantable devices), micro-fuel cells (μFCs) are considered as a promising alternatives to batteries as power sources.
