Testing of PEM Electrolyzer
The production of green hydrogen through electrolysis is internationally recognized as a key component of the energy transition, as green hydrogen can significantly reduce CO₂ emissions across entire industrial sectors. Primarily, three processes are used: AEL, SOEC, and PEM electrolysis. The latter is considered particularly mature and flexible and is increasingly being developed for large-scale applications. Reliable testing and inspection solutions at cell, stack, and system levels are essential for the success and optimization of this technology.
How can we support you?
We enable automated testing in the power range of up to 5 MW, providing extremely high currents while maintaining low voltages. Our many years of experience also allow us to respond to individual testing requirements and adapt our test stands to meet our customers’ needs. Do you have specific requirements for your PEM electrolyzers? Get in touch with us, and we will present our solutions to you. Our goal is to increase your productivity and support you in further penetrating the market for PEM electrolysis.
HORIBA FuelCon has decades of experience in providing reliable testing and inspection solutions. With our technology, we support the path toward the energy transition and present our solutions aimed at strengthening global testing capacities for electrolyzers. The foundation for testing efficient, durable, and scalable electrolyzers at our company lies in high-quality, long-lasting components combined with reliable safety features. A high pressure level increases system efficiency and allows further savings on additional compressors for the produced hydrogen. With our Evaluator EC and Evaluator ES series, we offer test stands for PEM electrolyzers with operating pressures of up to 100 bar.
