| Abstract Scope |
As the global population and energy consumption rise alarmingly, the demand for sustainable, low-carbon-emission energy conversion and storage devices, has dramatically increased. Because of the intermediate-temperature (300-600oC) operation, the protonic ceramic electrochemical devices have attracted increasing attention in recent years. However, challenges such as low manufacturing efficiency, high manufacturing costs, and limited dimensional and structural flexibility have hindered their scalability and commercialization. The microextrusion-based additive manufacturing technique offers a solution to manufacture protonic ceramic with versatile geometries and compositions. The paste preparation, printing parameters, and sintering conditions were carefully studied to ensure the successful manufacturing of protonic ceramic thin films, large-area tubes, microchannels, and heterogenous structures. The protonic ceramic parts demonstrate properties and performance comparable to or higher than those achieved by state-of-the-art methods. |
