Abstract

Herein, the general concepts of low-temperature fuel cells (LTFCs) are discussed, with special attention to proton exchange fuel cell (PEMFC) and anion exchange membrane fuel cell (AEMFC). LTFC has the potential to provide power to portable devices, transportation, and stationary sectors. With the aim to solve the principal catalytic problems at the anode and at the cathode of LTFCs, a fundamental study of the mechanism and kinetics of carbon monoxide and hydrogen oxidation as well as oxygen reduction on well-defined and practical catalysts in acidic and alkaline media is discussed. Consequently, the aim of the present work is not only to provide the new advances in the catalytic materials but also to understand the reactions occurring at fuel cell catalysts, which may help to improve the fabrication of novel electrodes in order to decrease the cost and to enhance the performance of LTFCs.
