AI Technical Summary

Technical Problem

Molten carbonate fuel cells face challenges in maintaining efficient operation and longevity at high CO2 utilization levels, leading to increased ohmic resistance and decreased cell voltage due to CO2 depletion, which can result in parasitic charge transport and degradation.

Method used

Incorporating a structural mesh layer with a contact area of 55% to 75% and a mesh open area of 25% to 45% between the cathode surface and the cathode current collector, providing improved electrical contact and mechanical stability while maintaining high CO2 transport selectivity.

Benefits of technology

The structural mesh layer reduces ohmic resistance and minimizes voltage loss over time, enhancing the mechanical stability and gas transport within the fuel cell, thereby improving overall performance and extending its operational lifespan.

Abstract

Molten carbonate fuel cell structures are provided that include a structural mesh support layer at the interface between the surface of the cathode and the cathode current collector. The structural mesh layer can have a mesh open area of 25% to 45%. In addition to providing structural support, the structural mesh layer can reduce or minimize ohmic resistance at the interface between the cathode and the cathode current collector.
