Nel Hydrogen

The PSM employs a modular approach to hydrogen production designed to offer guaranteed, repeatable performance per module to provide a cost-effective solution for hydrogen production at all scales.  It includes the PEM cell stacks, associated piping, DC power connections, and related critical monitoring instrumentation.

•  Plug and play containerized electrolyser stack module for easy plant integration
•  Site ready design eliminates the need for a building and reduces construction cost
•  Pre-integrated stacks reduce installation time and risk 
•  Instrumentation for critical process and safety monitoring included in package
•  Assembled and pre-tested at factory to assure quality control

The A485 stack consists of 230 cells assembled on a self-supporting rigid steel frame. As DC voltage is applied between the first and last electrodes, current flows through the cells, splitting water molecules to generate hydrogen and oxygen gas. 

Each cell is composed of an anode and a cathode, separated by a woven non-asbestos diaphragm which is integrated in a synthetic rubber frame. The gas from each cell is collected in the hydrogen and oxygen flow ducts which feed the gas into the electrolyte system. 

The electrolyte system consists of two gas separators, water seals, a lye circulation unit and a support frame. The main functions are to separate the gases (H₂ and O₂) from the lye coming from the cell stack and to cool and circulate the lye back to the stack. The electrolyte system is designed to serve a single atmospheric alkaline electrolyser cell stack. For large-scale plants the number of A485 stacks and electrolyte system modules are simply multiplied to obtain the required H₂ production volume.

The MC Series electrolysers deliver megawatt scale performance in a containerized form for easy outdoor installations. Nel’s PEM Technology makes for a reliable and turnkey solution with minimal maintenance. Depending on the model, the units can produce a maximum of either 246 Nm³/h or 492 Nm³/h of hydrogen gas at 99.9995% purity on-demand.
