Electrolyser Power, H2 production, Energy consumption, and flow rate calculator

Understanding the performance and operational dynamics of electrolyser cells or stacks is crucial for optimizing their efficiency. Our innovative smart calculator provides a comprehensive analysis by calculating key metrics such as hydrogen production rate, power and energy consumption, heat generated, and the theoretical water required for hydrogen production. Additionally, it estimates the flow rate of water or lye necessary to maintain optimal conditions in the electrolyser cell or stack, ensuring minimal overpotential.

Users can input parameters such as single cell voltage, total stack voltage, number of cells, current density, and the active area of each cell. The calculator then computes the total power used, hydrogen production rate, energy consumption, and the heat evolved during operation. By specifying the specific heat capacity (Cp) and temperature different between inlet and outlet of the electrolyser stack (ΔT), users can also determine the appropriate flow rate of water or lye required to maintain a uniform temperature across the stack.
