Abstract: Among the different types of fuel cells, the proton exchange membrane (PEM) fuel cells are considered to become dominant in the following years as they can operate with different combustibles (hydrogen, ethanol and methanol) and run at relatively low temperatures (70 – 90 ⁰C), thus being favorable for both stationary and mobile devices.Although the PEM fuel cell’s performance, cost and durability has improved significantly in the last two decades, the technology still presents a series ofdrawbacks, such as high material cost, sensitivity to contaminants and Pt dissolution.
This paper is a review of current status in the study of PEM fuel cells materials and includes the design, working principle and electrochemical processes. The paper presents the materials, various operating parameters (pressure, temperature and humidity), efficiency, polarization characteristics and power characteristics for this type of fuel cells. It also emphasizes the major challenges in PEM fuel cell technology development.
