Innovation and Objectives Innovation Task outline, technical objectives • Elimination of platinum group metals Yr Yr Yr Task and lead through use of anion exchange 1 2 3 membrane technology for fuel cells FC catalyst: PP, UNM and electrolyzers EC catalyst: NU, Proton, PP • Focus on the bifunctional hydrogen Electrode: Proton, EWII, PP electrode as the critical remaining enabler to low cost materials T2M: PP, Proton, EWII Tech-to-Market strategy Short-term: high-value, fault tolerant electrolyzers, electrodes and catalysts for specialty markets. Long-term: reversible fuel cell and components for renewable storage.
Innovation and Objectives Proposed targets Project history Metric S.o.t.A Proposed The partners have been working on Voltage,0.35A/cm 2 0.4 V 0.65 V different interrelated projects together (fuel cell) and have combined to solve the last Voltage, 0.5A/cm 2 2.4 V 2.1 V piece of the project. (electrolyzer) Progress has been steady, with electrolyzer progress ahead of schedule $/kW at stack level $400 $50 and fuel cell progress accelerating. (AEM vs PEM) (PEM) (AEM) Desirable partnerships Anticipated challenges 1. Improved AEM materials and Electrode structure optimization and electrode structure diagnostics. stability of AEM materials have been 2. Alternate uses and applications of challenging. We are therefore the catalytic materials, electrodes, addressing catalyst/electrode and and systems developed electrode/AEM materials separately.
