We believe clean hydrogen is key to mastering the transition to a low-emission and sustainable energy system for the global economy. That's why we offer precious metal services, electrocatalysts and catalyst coated membranes for proton exchange membrane (PEM) Electrolysis and PEM Fuel Cells for clean hydrogen generation and use. To ensure circularity, we are developing innovative solutions to recycle electrolyzer and fuel cell components.

High Performance Materials for Proton Exchange Membrane (PEM) Electrolyzers

Ideal for dynamic and decentralized hydrogen production, offering rapid response times, high efficiency, and compact system design. Ability to operate under high pressure and variable loads making it well-suited for various energy sources. PEM electrolyzer stacks set the standard for performance, durability, and purity in clean hydrogen generation

High Performance Electrocatalysts for low temperature PEM (LT-PEM) Fuel Cells

Platinum based electrocatalysts on advanced carbon supports high performance and durability in heavy- and light-duty applications

Leading enabler for high temperature PEM (HT-PEM) Fuel Cells

Aviation, heavy duty and stationary applications benefit from HT-PEM Fuel Cells offering simple thermal and water management, high robustness and tolerance to feed gas impurities. Celtec-MEA is the benchmark for this technology.

Focus on reducing cost and improving performance

We strive for innovative material solutions with lower cost and improved efficiency to enable scaling of clean hydrogen generation and use. To realize this target, we will decrease platinum group metal loadings of electrocatalysts and enable sustainable circular solutions.
