An electrolyzer cell is the basic functional unit within an electrolyzer, where the electrochemical reaction of water splitting into hydrogen and oxygen occurs. Hyto Energy’s electrolyzer cells are precision-engineered to optimize reaction efficiency, durability, and hydrogen purity, forming the core of their electrolysis systems. In alkaline electrolyzer cells, the design features two electrodes (anode and cathode) immersed in an alkaline electrolyte (e.g., KOH solution). The anode facilitates the oxidation of water to oxygen, while the cathode drives the reduction of protons to hydrogen. A separator, often a porous diaphragm, prevents the mixing of hydrogen and oxygen while allowing ion transport, ensuring safe and efficient operation. These cells are known for their robust construction, enabling long-term operation under high temperatures and pressures. PEM electrolyzer cells, on the other hand, incorporate a proton exchange membrane as both the electrolyte and separator. The membrane is sandwiched between catalyst-coated electrodes (typically platinum-based), enabling selective proton conduction from the anode to the cathode. This design eliminates the need for liquid electrolytes, simplifying cell structure and enhancing hydrogen purity. Hyto’s PEM electrolyzer cells are designed for high current density, supporting high hydrogen output per unit area, which is crucial for compact system designs. AEM electrolyzer cells, an innovative focus, use an anion exchange membrane to conduct hydroxide ions. They feature non-precious metal catalysts (e.g., nickel-based) on the electrodes, reducing material costs while maintaining efficient ion transport. The cell structure balances the simplicity of alkaline cells with the performance of PEM cells, making them a promising option for cost-sensitive applications. Each type of electrolyzer cell from Hyto is tested for performance under various operating conditions, ensuring reliability across different applications.
