Why PEM?
Welcome to the future of sustainable hydrogen production with PEM electrolyzers! As a discerning investor or client, you'll be thrilled to learn about the myriad advantages that Proton Exchange Membrane (PEM) electrolyzers offer over other technologies in targeted applications. Unlike traditional methods, PEM electrolyzers excel in efficiency, scalability, and environmental friendliness. With their rapid response time and dynamic load-following capabilities, PEM electrolyzers ensure optimal energy usage, saving you costs in the long run. The compact and modular design allows for seamless integration into existing infrastructures, enabling hassle-free scalability to meet growing hydrogen demands. Moreover, PEM electrolysis operates at lower temperatures, ensuring enhanced safety and prolonging the lifespan of the system’s internal components. The absence of corrosive materials and minimal maintenance requirements make PEM electrolyzers a sound and sustainable investment due to its lower operating expenditures. Join us in revolutionizing the hydrogen landscape with cutting-edge technology that paves the way for a cleaner and brighter future.
How PEM Works?
Water is supplied to the anode using a reciprocating pump where it is oxidized due to an electrical current supplied to the stack to produce oxygen and hydrogen gas: H2O → 2H+ + ½ O2 + 2e-. The proton exchange membrane only conducts hydrogen cations which receives an electron at the cathode side: 2H+ + 2e- → H2 and then reduces again to form molecular hydrogen. The overall total reaction, 2H2O → H2 + ½ O2, results in a hydrogen gas flow twice as high as the oxygen flow rate. Hydrogen and Oxygen gas are both diatomic and thus consists of two atoms. Every 9 L of water will produce 8 Kg of Oxygen gas and 1 Kg Hydrogen gas, which contains the equivalent of 33.33 kWh of energy (LHV).
