DEEE0011324

The overall project goal is to advance GORE’s ultra-thin diaphragms from Technology Readiness Level (TRL) 3 to TRL 5 in service of two primary objectives:

1) To meet or exceed DOE’s next-generation liquid alkaline water electrolyzer (LAWE) performance targets (2 A/cm² at = 1.7 V with = 2.1 mV/KH degradation) by optimizing ultra-thin diaphragms and pairing them with state-of-the-art electrodes,

and

2) To de-risk the ultra-thin diaphragms for scale-up at GORE to establish a domestic supply chain of advanced LAWE separators.

Expected outcomes are:

• Pilot-scale rolls of ultra-thin diaphragms with optimized structure and composition,

• Deeper understanding of diaphragm property-structure-property-performance relationships,

• Data from single cells and a small stack demonstrating that DOE targets have been met,

• A technoeconomic analysis of new diaphragms on LAWE stack capital and operating costs,

• Collaborative relationships among industry leaders to commercialize new LAWE technology, and

• A more diverse and well-trained workforce, more capable facilities, and more involved community.
