PGM-Free Anodes for AWE
Nickel-based anodes for alkaline water electrolysers. No platinum-group metals, high oxygen evolution activity, stable under intermittent renewable power.
Green Hydrogen
Electrodes for AWE & AEM electrolysers
The full range of SPARKFUZE™ anodes and cathodes for alkaline and Anion Exchange Membrane electrolysis — PGM-free or low-PGM, wide-format up to 2.7×1.8 m, engineered for efficiency and a 10-year+ service life.
Why it matters
Cutting the cost of the clean-fuel revolution
Green hydrogen currently costs 4–5× more than fossil fuels. Electrodes are one of the biggest cost levers — and that is exactly where SPARKFUZE™ rewrites the economics.
Products
The full hydrogen electrode range
From PGM-free AWE anodes to high-performance AEM cathodes — one process, tailored to your stack.
PGM-Free Anodes for AEM
Next-generation anodes engineered specifically for Anion Exchange Membrane electrolysers, combining low cost with high OER efficiency.
Low-PGM Cathodes
Hydrogen evolution cathodes with drastically reduced platinum-group loading. Same performance, lower bill of materials and supply-chain risk.
High-PGM Cathodes
Ultra-high-performance cathodes for customers prioritising peak efficiency. Fine-tuned PGM loading deposited uniformly by SPARKFUZE™.
Cathodes for AEM
Dedicated cathodes optimised for AEM cell chemistry — matched to Jolt AEM anodes for a fully integrated electrode pair.

Benefits
Built for the realities of industrial hydrogen
Wide-format substrates
Coating capability up to 2.7 × 1.8 m — large enough for today's stacks and tomorrow's gigawatt-scale designs.
Large-scale production
Automated lines with up to 400,000 m²/year capacity, deployable close to your stack assembly.
Higher efficiency
High ECSA coatings deliver lower overpotentials — less electricity per kg of H₂.
10-year+ durability
Robust adhesion between catalyst and substrate resists cycling and chemical stress — lower replacement cycles.
Renewable-coupling ready
Designed to operate under the intermittent, variable loads typical of wind and solar-powered electrolysers.
Stable supply chain
PGM-free and low-PGM chemistries reduce dependency on volatile precious-metal markets.
Lower total cost
Less catalyst, less energy to manufacture, longer life — a stack-level CAPEX and OPEX reduction.
