Title: Hybridization of Freeze Casting with Additive Manufacturing for Simplified Production of High Performance SOFCs

Abstract

This report discusses research and development activities undertaken by Glacigen Materials, Inc. and Montana State University during the performance of a DOE Phase I STTR award. The objective of this project was to develop a manufacturing process by hybridizing the existing processes of freeze casting and additive manufacturing to enable facile and inexpensive production of high performance solid oxide fuel cells (SOFCs). The objective simultaneously addresses two barriers to the commercial implementation of SOFCs. First, the project demonstrates a method which allows SOFCs to be produced at dramatically decreased costs; and second, demonstrates a cell architecture which has the potential to substantially increase the specific power density of cell stacks of that which is currently available. The latter is of particular importance to mobile/transport applications. In short, the project was highly successful, meeting the basis of proposed technical objectives. Refined electrochemical results are being pursued in the month that remains in the project at the time of this interim report writing. Further, unanticipated results exacerbated the technical merit of the manufacturing technique. The freeze casting used in this work actually leverages the closely related freeze tape casting technique and so the hybridization with the additive manufacturing process will be referredmore » to as FTC-AM. Within the Phase I work, FTC-AM of high performance SOFC electrodes was demonstrated successfully and these components were used to assemble unit cells. Chemical doping of the SOFC electrolyte enabled low temperature processing of the entire cell in a single step. A first electrochemical test demonstrated a generation of voltage, but the electrolyte failed during reduction. Additional electrochemical testing is taking place in the 6 weeks that remains in the project. Glacigen’s work has attracted commercial interest, in part, leveraging the results of this project. In the case of one potential customer, the interest is derived from this project directly. These interactions, and equipment sales, create a compelling story for the value of this advanced manufacturing technique and its full development.« less
