Hyfindr Tech Talk # 34 - PEM Electrolyzer Systems - Hydrogen Production Technology Explained

In this tech talk, Steven had the pleasure of discussing about PEM electrolyzers with Max Ellerich, Solution Manager H2 Production at NEUMAN & ESSER Group.

Learn about PEM Electrolyzer Systems

Steven Oji and Max Ellerich delve into the  a comprehensive overview of PEM electrolyzers, focusing on their function, components, operation, and future prospects. Max elaborates on PEM electrolyzers, describing them as machines that use water and electricity to produce green hydrogen through a process involving water splitting..

The video also explains the inner workings of a PEM electrolyzer, starting from individual cells where water is split into oxygen and hydrogen through the application of voltage and catalysts. He details the role of proton exchange membranes in separating hydrogen from oxygen, emphasizing the importance of water quality and temperature control for optimal electrolysis. Max further discusses scaling up electrolyzer systems by stacking multiple cells to increase hydrogen production.

The conversation delves into the broader system layout, including water treatment, cooling, and purification processes essential for efficient electrolysis. Max emphasizes the significance of maintaining water purity and optimal operating conditions to prevent degradation of stack components. He also highlights the role of power electronics in transforming and rectifying voltage for electrolysis. Visual aids, including images of electrolyzer systems and their components, enhance understanding.

Max presents examples of real-world applications, such as a 1.3 MW electrolyzer deployed alongside a coal power plant in Brazil. The need for standardization and industrialization to meet growing demands for hydrogen production.
