Electrolyzers
SSBGE provides customized electrolyzer solutions based on specific requirements and applications.
An electrolyzer is a device that uses electricity to split water (H2O) into its two constituent elements, hydrogen (H2) and oxygen (O2), through a process called electrolysis. The electrolysis process involves passing an electric current through a water electrolyte, which can be either an acidic or alkaline solution. The electric current splits the water molecules into their constituent elements: hydrogen gas bubbles up at the cathode (negative electrode) and oxygen gas bubbles up at the anode (positive electrode).
There are two types of electrolyzers:
AEM Electrolyzers (Anion Exchange Membrane)
The AEM electrolyzer uses a solid polymer electrolyte, typically made of a fluorinated polymer, which allows for the selective passage of anions while blocking the passage of cations. This allows for the production of high purity hydrogen gas, which can be used in a variety of applications, including fuel cells.
PEM Electrolyzers (Proton Exchange Membrane)
PEM electrolyzers use a solid polymer electrolyte membrane, typically made of a perfluorinated sulfonic acid polymer, which selectively conducts protons while blocking electrons and other species. This allows for the production of high purity hydrogen gas, which can be used in a variety of applications, including fuel cells.
AEM Electrolyzers
Compared to other types of electrolyzers, the AEM electrolyzer offers several advantages, including lower capital and operating costs, higher energy efficiency, and greater flexibility in terms of operating conditions. AEM electrolyzers are also relatively easy to scale up, making them well-suited for large-scale hydrogen production.
PEM Electrolyzers
PEM electrolyzers are compact, efficient, and easy to operate, making them well-suited for small-scale and distributed hydrogen production. They can be used in a wide range of applications, from hydrogen refueling stations for fuel cell vehicles to energy storage systems for renewable energy sources.
PEM electrolyzers have several advantages over AEM electrolyzers, including higher efficiency, faster response times, and the ability to operate at higher pressures.
Hydrogen produced through electrolysis can be a clean and sustainable source of fuel, especially if the electricity used to power the electrolyzer comes from renewable sources such as solar or wind. However, the cost of electrolyzers and the infrastructure required for hydrogen storage and transport remain major challenges to the widespread adoption of this technology.
