Efficient and Sustainable Paradigm for MW-hr. Electric Propulsion (ESP for MEP)

PCI is proposing an advanced solid oxide fuel cell (SOFC) that efficiently converts the energy in H2 or liquid fuels into electrical energy. The technology is specifically targeted for sustainable electric air propulsion (EAP) needs. The technology is significantly more power dense than other systems in development and is a higher efficiency, higher power density (gravimetric and volumetric) and lower cost compared to alternatives e.g., low temperature proton exchange membrane fuel cells and batteries. During Phase I, a feasibility study, including validation of advanced SOFC performance that meets exceeds solicitation requirements (i.e., cell power density ≥0.80 W/cm2 for ≥60 min continuous, and ≤10 μV/h degradation over 250 h at peak power density) will be confirmed. A system model and stack design suitable for EAP will be identified in Phase I. Experimental data and modelling will be used to verify compliance in Phase I for meeting dynamic EAP loads. During Phase II, performance metrics will be rigorously examined, including long-term durability and potential to meet NASA requirements. A 1 kW prototype will be fabricated, demonstrated, and delivered. to NASA. The technology is being developed for other applications and the proposed effort will leverage those advances to mitigate risk of failure.
