ACS SHALL BUILD AN ALL-IN-ONE ANODE PACK MANUFACTURING PILOT LINE INCORPORATING: 1) SINGLE-STEP DIFFUSION BONDING: DEVELOPMENT OF BONDING THE POROUS TRANSPORT LAYER (PTL), FLOW FIELD, AND BIPOLAR PLATE INTO AN ANODE PACK IN A SINGLE DIFFUSION BONDING (DB) STEP. 2) SINGLE-PASS IN-LINE PVD COATING: IMPLEMENTATION OF AN IN-LINE PHYSICAL VAPOR DEPOSITION (PVD) COATING SYSTEM CONSISTING OF MULTIPLE CHAMBERS APPLYING MULTIPLE COATINGS FOR EACH PACK. THE COATING LINE WILL COAT THE PTL SIDE WITH PLATINUM IN ONE CHAMBER, AND THE SEPARATOR SIDE WITH GOLD IN A FOLLOWING CHAMBER FOR AN OVERALL THROUGHPUT OF < 5 MINUTES PER PACK. 3) MICROEXPANDED PTL: ACS WILL DESIGN, EXPAND, STACK, DIFFUSION BOND, AND PT COAT PTLS USING MICROEXPANDED MESH AND INCORPORATE THE ACS-DESIGNED MICROEXPANDED PTL INTO ANODE PACK FABRICATION. TO ACHIEVE THE PROJECT OBJECTIVES, TASKS ARE SCHEDULED OVER 3 BUDGET PERIODS (BP1, BP2, AND BP3) OF 18 MONTHS, 18 MONTHS, AND 12 MONTHS OVER A PERIOD OF 4 YEARS. IN ADDITION TO TECHNICAL OBJECTIVES, THIS PROJECT INCLUDES COMMUNITY OBJECTIVES TO BENEFIT THE DISADVANTAGED COMMUNITIES AROUND LINCOLN, RI, THE PRIMARY LOCATION OF PROJECT ACTIVITIES, AND AROUND A US-BASED ACS MANUFACTURING FACILITY.
