A PEM electrolyser (Proton Exchange Membrane electrolyser) is an advanced hydrogen production device that uses a proton exchange membrane as the electrolyte, enabling efficient and high-purity hydrogen generation. Hyto Energy’s PEM electrolysers are designed for performance, flexibility, and integration with renewable energy sources, making them a key technology in green hydrogen production. The core of a PEM electrolyser is the proton exchange membrane, a thin polymer sheet that conducts protons (H⁺) from the anode to the cathode while blocking electrons. This membrane is sandwiched between two catalyst-coated electrodes (typically using platinum or iridium), where the electrochemical reaction occurs: water is split at the anode to produce oxygen, protons, and electrons, while protons and electrons combine at the cathode to form hydrogen gas. This design ensures high hydrogen purity (up to 99.999%) with minimal impurities, eliminating the need for extensive post-processing. A major advantage of Hyto’s PEM electrolysers is their rapid response to changes in electrical input, allowing them to efficiently utilize the variable power output from renewable sources like solar and wind. This makes them ideal for distributed green hydrogen projects, where they can be installed near the point of use (e.g., fueling stations, industrial facilities) to reduce transportation costs. Their compact and modular design also enables easy scalability, with systems ranging from small residential units to large industrial plants. PEM electrolysers operate at relatively low temperatures (60–80°C), reducing energy losses and simplifying thermal management. Hyto’s focus on material science ensures that their PEM electrolysers offer long durability, even under frequent cycling, making them a reliable choice for both continuous and intermittent operation.
