His work focuses on enhancing the performance and cost-effectiveness of fuel cell technology.

Latest Patents

Coimbra's latest patents include advancements in anode-supported solid oxide fuel cells using a cermet electrolyte. This invention involves a novel solid oxide fuel cell article and method of manufacture that improves properties at lower costs. The structural features include fabricating an anode, applying a cermet electrolyte, and a cathodic layer. The cermet electrolyte, which contains a small amount of transition metal, reduces thermal expansion mismatch with the anode. This allows for a graded structure of electrochemically active substances across the anode/electrolyte structure. Under operating conditions, a dense electrolyte and metal oxide sub-layer exist on the oxidized side, while the reducing side features a porous sub-layer containing transition metal. This tailored approach enhances power output and electrochemical performance while maintaining structural integrity.

Another significant patent involves solid oxide fuel cells with novel internal geometry. This invention features a fuel electrode-anode supported type SOFC with improved mechanical and electrochemical properties. The supporting anodes include internal longitudinal elevations or bosses that project inwardly into the central bore of the tubular body. This design increases electrode surface area, optimizes anode electronic conductivity, and facilitates the mounting of the cell into a SOFC assembly system. The SOFCs can take on various tubular configurations, including cylindrical and polygonal shapes, and the low-cost manufacturing routes disclosed do not require additional processing steps compared to conventional techniques.
