Fraunhofer Institute for Ceramic Technologies and Systems IKTS
The Fraunhofer IKTS develops miniaturized and robust water electrolysers for the local production of combustion gases (H2, O2). This enables the decentralized applications of relevant systems (e. g. flame ionization detector) as field devices, for instance. The investigated electrolyser uses a polymer-electrolyte-membrane (PEM) to dissociate the water molecule. The PEM-component is fixed in a ceramic package based on the ceramic multilayer technology (here: LTCC), consisting of a gas distribution device, terminations and seal. In addition, this approach provides the integration of sensory elements (e. g. temperature, pressure,…) for a more precisely control of the electrolyzing process.
