HORIZON-JTI-CLEANH2-2024-01-01: Innovative proton conducting ceramic electrolysis cells and stacks for intermediate temperature hydrogen production

CENER technical contribution could any of these:

• Manufacturing of proton conducting ceramic electrolysis cells (PCCEL) by functional printing, and prototyping at preindustrial scale (2kW) by roll-to-roll technology.

• Modelling, simulation, design and fabrication of optimized stack components, specifically adapted to proton conducting ceramic cells.

• Modelling the behaviour (i.g. degradation at high temperature) of obtained cells and stack by CFD software, just helping to a more efficient design of new cells and stacks.

• Electrochemical testing of obtained cells and stacks at high temperature. HyGrIn lab has equipment for testing them at several scales, from small (button cells and 5x5 or 10x10 cm2 cells) to large stacks (5 to 10 kW), reaching 1000 ºC. Faradic efficiency and degradation rates of PCCELs would be complemented with analytic characterization (post-mortem analysis, microstructure and composition, etc).

• Techno-economic analysis of developed stack prototypes, including CAPEX and OPEX analysis
