Description
This facility has capabilities for design and fabrication of optimized chassis and materials assemblies for water splitting devices. They include a polymer 3-D printer (Connex 350 3D Printer with Water Pressure Cleaner; model: Connex 350/1077L, vendor: Objet) for chassis construction, a database of compatible materials such as plastics and epoxies, and custom tooling for mounting device components during assembly.
Capability Bounds
10x10 cm2 or smaller
Unique Aspects
Capability permits going from water splitting device concept to demonstration in house.
Availability
Facility is in use for JCAP's program but can accommodate additional projects.
Benefit
This capability is central to fabrication of integrated photoelectrochemical devices for water splitting.
