The mixture of ceramic, binder and solvent that evaporates at different rate allows you now to 3D print a solid oxide fuel cell. This ink is developed by researchers at Northwestern University. Prof. Ramille Shah is the man behind the ink, which allows 3D printing of all individual components of a fuel cell - anode, cathode, electrolyte and interconnects.
This work was shown at the Material Research Society fall meeting at Boston this week by Adam Jakus, a Ph.D. at Shah's lab. The use of 3D printing has allowed them to print in new shapes and designs which the conventional methods don't allow. They have been able to generate really dense packed particle structure in the 3D printed models. Moreover, 3D printing allows them to use new designs which might increase the surface area and hence the transport of charge or increase the efficiency. This can be one of the breakthroughs in use solid oxide fuel cell to convert gas into electricity.

Also, the team has developed a ink to 3D print GRAPHENE!
