Protonic-ceramic fuel cells and electrolyzers: Scale-up, degradation and high-pressure operation
Proton-conducting ceramics are emerging as an enabling material for efficient electricity generation, energy storage, and fuels synthesis. While recent advancements at the lab-scale are highly encouraging, there are few reports of scaling cell size beyond the button cell, and limited demonstrations of multi-cell stacks. The first part of this work is focusing on scaling up protonic-ceramic devices. The order-of-magnitude increases in the physical size of the delicate membrane-electrode-assembly (MEA) bring concerns regarding mechanical-strength and robustness. Consequently, the compatibility of ...
