In House Reactor Design

At ELCAT every reactor used, is made in house i.e. electrolyzers, fuelcells, H-cells, photoelectrochemicalreactors, batteries, 2D and 3D electrodes,..

Develloping a reactor starts with an initial discussion and which leads to a first CAD design, afterwards this CAD design will be transformed in a first rendered 3D reactor with every part visible. If the design suffice to all needs we start the engineering design in order to construct the reactor. For this a wide variety of machines and tools, are used at ELCAT. A CNC micromilling machine, 3D printer (plastic and metal), casting, and our newest state of the art 5-axis femtosecond micromachining laser are the most used. It’s possible to make reactors from micro to decimeter scale with these machines. On top of that the micromachining laser enables us to change the surface structure on picoscale.

When the first prototype is finished, ELCAT can test, characterize, and afterwards optimize the reactor for a next generation.


The BECO2ME is a modular reactor, which means that it can be used as an flow-by, zero gap, and flow through reactor.

In our lab this reactor is used to measure catalysator stabilities, in a CO2 to formic acid. 

3D printers are an essential part within ELCAT, making custom one part plastic pieces possible. 3D printers are used for custom spacers, casting,..

When electrodes are too hard to manufacture with the milling machine an in house developed casting technique is used to manufacture titanium, nickel, and SSTL electrodes.

With the micromilling machine, ELCAT is able to construct batteries, modular reactors, holders,.. without being limited by the material.
