Additively manufactured fuel cells

Important results from the project

** Denna text är maskinöversatt ** The overall goal was to evaluate whether the additive manufacturing technology was applicable to solid phase fuel cells (SOFCs) with an innovative design. A suspension has been developed which has been used to make an electrolyte material of Zirconia with additive technology. The produced materials have shown both good mechanical properties and could be designed as thin structures. Finally, thin coatings of, among others, Lantan Strontium Manganat (LSM) have been applied to the surface of the electrolyte material.

Expected long term effects

** Denna text är maskinöversatt ** With the manufacturing process that has been developed and verified to work to produce the geometric shapes with the materials used in a solid-phase fuel cell, several of the uncertainties that previously existed about this concept have been able to be dispelled. Many of the basic preconditions for a further development of innovatively designed solid-phase fuel cells are now in place, which is an important part of being able to justify further development by developing a working prototype.

Approach and implementation

** Denna text är maskinöversatt ** An important part of the work has been to find a resin composition that works well throughout the manufacturing process that includes both the additive and the subsequent thermal processes. The big breakthrough was when the understanding of how the resin and the subsequent processes interact, which now makes it possible to produce the materials needed. The printed materials and coatings have been evaluated, mechanically, microstructurally (SEM) and with respect to surface structure with interferometer.
