1. Basic Principles of Proton Exchange Membrane Fuel Cells Proton exchange membrane fuel cells, also known as polymer electrolyte fuel cells, are a type of low-temperature fuel cell that operates at relatively low temperatures (typically below 100 degrees Celsius). This makes them highly versatile in their applications, ranging from powering vehicles to providing backup power … Continue reading Detailed Explanation of the Structure and Principle of Proton Exchange Membrane Fuel Cells
