Better performance for a better future

JOLT’s technology is a competitive coating treatment that can be applied to electrode supports in electrolysers & fuel cells. Such a process produces metal oxides with significantly improved performance at a reduced cost.



Standard manufacture consists in printing a catalyst’s ink onto the electrode. To do so, three main steps are involved. In contrast, JOLT exploit a self-supported methods which merges the catalyst synthesis with the deposition step. The advantage is to create an intimate contact between the catalyst layer and the support, avoiding the use of binders, to improve the catalytic performances.

Jolt’s technology overcomes all the limitations present in other technologies. Our process shares the positive features of the wet chemistry arising from sol-gel and the easiness of a thermal process with the advantage of reducing the energy input (temperatures between 180°C – 250°C).

The first sample on the left is prepared according to a conventional thermal decomposition method, while the second one is prepared according to our proprietary method. In the first case the surface is completely flat, with some cracks. Instead, the JOLT approach ensures the formation of a catalyst layer owing a nanostructured morphology with high roughness and porosity. This enhances the surface area without introducing instability point in the overall microstructure. In short, it is a compromise between nanostructuring and stability.

More durable

More Durable: Our electrodes are designed to provide reliable results for at least 10 years without showing any degradation in performance. Our Accelerated Degradation Tests are carried out under the most demanding conditions to meet any of our customers requirements.

Better performance

The electrodes represent the heartbeat of the electrolysers, determining the device’s performances and lifetime. The possibility to lower the electrodes overative voltage at a given current translates into reduced energy demand for the water splitting process and therefore an increment in the energy efficiency.
JOLT’s first electrode generation showed a 10-15% improvement in voltage efficiency over comparable “best in market” electrodes, constituting a huge leap forward in performance that is outside the scope of traditional electrode technologies.
The team are continuing to refine and improve the catalyst ink. Current best electrodes are showing an overall voltage efficiency of 75 – 85%
