Advanced Materials in Energy Conversion Devices
Fuel Cells and Biofuel Cells
A fuel cell is, in its most basic sense, a device that transforms chemical energy into electrical energy, whereas a biofuel cell is a subcategory of a fuel cell that uses a biocatalyst. The ideal candidate to replace current energy technologies is thought to be fuel cells. Fuel cell systems have a wide range of potential uses, including stationary power generation, transportation, and renewable energy storage when used in reverse as electrolyzer. Additionally, carbon capture and utilization (molten carbonate fuel cells) and power to gas processes involving the co‐electrolysis of CO 2 and H 2 O are good candidates for high‐temperature fuel cells (solid oxide fuel cells and electrolyzer). Low‐temperature biofuel cells are a great example of bio‐compatible energy systems. Only highly developed and effective catalytic materials in both the anodic and cathodic positions enable the use of various fuel types (gas or liquid, hydrogen or hydrocarbons), an extension of lifetime, and a reduction in operating temperature. A new era of metal‐free and/or nanostructured electrodes has significantly advanced fuel cell technology. In this regard, the current chapter offers comprehensive information on the cutting‐edge materials utilized in fuel cell technology. Additionally, a classification and overview of fuel cells are given in this chapter, along with details on their major uses and the equations governing their primary reactions. In the end, the goals for further development of advanced materials for both mobile and stationary fuel cell applications, as well as the problems with cost and reliability, have been thoroughly discussed.
