Proton Exchange Membrane Fuel Cells – Advanced PEM fuel cells for automotive, stationary, and portable power applications.

Proton exchange membrane fuel cells (PEMFCs) are the most common and commercially advanced type of fuel cell. They operate at relatively low temperatures (around 80°C) and use a solid polymer electrolyte membrane to conduct protons from the anode to the cathode. This low-temperature operation allows PEMFCs to be more compact, lightweight, and have a quicker start-up time than other types of fuel cells.

The dominance of PEMFCs is particularly evident in the transportation sector, where their high power density and ability to handle a dynamic load make them an ideal choice for vehicles. Ongoing research and development are focused on improving the durability and reducing the cost of PEMFCs, particularly by developing new materials for the catalyst and membrane.
