THE TECHNICAL GOAL IS TO DEMONSTRATE THE ACCELERATED DISCOVERY, DESIGN, AND LASER CONVERGENT MANUFACTURING OF LOW-TEMPERATURE (< 650°C) OXYGEN-CONDUCTING SOLID OXIDE ELECTROLYZER CELL(LT-O-SOEC) WITH A MINIMUM ACTIVE AREA > 15 CM2, TO ACHIEVE OR EXCEED THE TARGETS OF = 1.2A/CM2 AT 1.3 V/CELL WITH = 3 MV/KHR DEGRADATION RATE. THE GOAL OF THE COMMUNITY BENEFITS PLAN (CBP) IS TO HELP ENSURE THE RESULTS FROM THE PROJECT HAVE A WIDE AND EQUITABLE POSITIVE IMPACT ACROSS UNITED STATE (US) COMMUNITIES WHILE AVOIDING INEQUITABLE NEGATIVE IMPACTS ON ANY SPECIFIC COMMUNITY, PARTICULARLY THOSE HISTORICALLY AT RISK FROM ENERGY-RELATED TECHNOLOGIES OR DEINDUSTRIALIZATION. TO ACHIEVE THE ABOVE-STATED PROJECT GOAL, WE WILL ACHIEVE THE FOLLOWING OBJECTIVES: DURING BUDGET PERIOD 1: OBJECTIVE 1: DESIGN AND VALIDATE THE PERFORMANCE OF NOVEL ELECTROLYTE, ELECTRODE, BUFFER MATERIALS AND INTERFACES. OBJECTIVE 2: HIGH THROUGHPUT FABRICATION, CHARACTERIZATION, AND TESTING OF MICRO-SAMPLE ARRAY TO (1) EFFICIENTLY SCREEN AND DOWN-SELECT VAST COMBINATORY POSSIBILITIES OF INTERFACE, MICROSTRUCTURE, AND CELL ARCHITECTURE FOR OPTIMAL PERFORMANCES; AND (2) QUICKLY ESTABLISH OF DATASETS OF PROCESSING-MATERIAL-PERFORMANCE LINKS FOR MACHINE LEARNING (ML) TRAINING. DIVERSITY, EQUITY, INCLUSION, AND ACCESSIBILITY (DEIA) OBJECTIVE 1: “RECRUITMENT”. SUPPORT RECRUITMENT ACTIVITIES TO ENSURE EQUITABLE OPPORTUNITIES FOR STUDENT RESEARCHERS FROM DIVERSE COMMUNITIES. ENERGY EQUITY OBJECTIVE 2: “HYDROGEN-ORANGE START-UP PRIZE.” INITIATE AND AWARD THE “HYDROGEN-ORANGE PRIZE” EACH YEAR TO THE TEAM OR INDIVIDUALS TO PRESENT THE MOST VIABLE BUSINESS OPPORTUNITY RELATED TO HYDROGEN AND CLEAN ENERGY TECHNOLOGIES. WORKFORCE OBJECTIVE 2: “RESEARCH EXPERIENCE FOR TEACHERS (RET) SUPPLEMENT.” PROVIDE A NEW OPPORTUNITY FOR 1 OR 2 ADDITIONAL TEACHERS PER YEAR TO PARTICIPATE AND WORK ON PROJECTS RELATED TO CLEAN ENERGY AND HYDROGEN RESEARCH. DURING BUDGET PERIOD 2: OBJECTIVE 3: ESTABLISH AND VALIDATE ML MODELS TO PREDICT AND DESIGN THE MATERIALS AND INTERFACE FOR THE HIGH-PERFORMANCE LT-O-SOEC, AND THE APPROPRIATE PROCESSING PARAMETERS FOR THE ULTRA-FAST, LASER-SELECTIVE CONVERGENT MANUFACTURING (ULCM) OF LT-O-SOEC. OBJECTIVE 4: COMPUTATIONAL MODELING TO PREDICT THE DEFECT-FREE LASER PROCESSING PARAMETERS AND DESIGN THE OPTIMAL THERMOMECHANICAL STABILITY AT BOTH MEMBRANE ELECTRODE ASSEMBLY (MEA) AND STACK LEVELS. OBJECTIVE 5: ESTABLISH ML-BASED, IN-PROCESS MONITORING OF MICROSTRUCTURE AND DEFECTS FOR QUALITY ASSURANCE. DEIA OBJECTIVE 2: “MENTOR-LEARNER.” ESTABLISH A DEIA “MENTOR-LEARNER” PROGRAM, MATCHING RESEARCHERS (GRADUATE, SMALL BUSINESS) WITH THE DIVERSITY OF NEXT-GENERATION LEARNERS (SCHOOLS, TEACHERS, ETC.). ENERGY EQUITY OBJECTIVE 1: “SUMMER ENERGY EQUITY WORKSHOP AND PROJECT.” ESTABLISH A WORKSHOP EACH YEAR, FOCUSING ON CHALLENGES AND OPPORTUNITIES TO ADVANCE ENERGY EQUITY THROUGH HYDROGEN AND RELATED CLEAN ENERGY TECHNOLOGIES. DURING BUDGET PERIOD 3: OBJECTIVE 6: ULCM OF LARGE AREA (> 15 CM2) MEA WITH PRECISELY CONTROLLED MICROSTRUCTURE AND CRYSTALLINE PHASE OF DENSE ELECTROLYTE, POROUS ELECTRODES, AND HETEROGENEOUS INTERFACE. OBJECTIVE 7: SOEC STACK PACKAGING AND TESTING TO VALIDATE THE LONG-TERM PERFORMANCE STABILITY OF LT-O-SOEC STACKS.
