abstract = {The metal-supported reversible proton ceramic cell (MS-rPCC) combines the dual advantages of metal support and proton conduction. It can simultaneously achieve efficient low-temperature operation, high mechanical strength, and excellent thermal cycling stability. However, a critical challenge in MS-rPCC fabrication lies in the element diffusion from the metal support and the mismatch between the metallic and ceramic layers. To address this, a rationally designed pure Ni metallic support combined with a transition layer (80 wt% NiO–20 wt% BaZr0.1Ce0.7Y0.2O3−δ (BZCY)) was introduced to engineer the interface, improving the strength and structural stability of MS-rPCC. The cell achieved a peak power density (P) of 0.8 W·cm−2 in fuel cell (FC) mode at 650 °C and a current density (I) of −1.25 A·cm−2 at 1.3 V in electrolysis cell (EC) mode. The cell exhibited no significant degradation in FC mode after 200 h of operation, with a degradation rate of 0.02 mV·h−1. The cell demonstrated exceptional stability during 100 h of reversible fuel cell/electrolysis cycling, thermal cycling, and rapid startup tests. This work provides a new approach for the commercialization and widespread adoption of MS-rPCC for low-temperature, high-performance power generation and hydrogen production.}
