Latest Patents
Stephan G Braun holds a patent for a unitized fuel cell structure. The purpose of this invention is to extend the edge of an electrochemical cell with a laminated plastic structure, providing strength and rigidity for sealing and support. This invention is particularly applicable to polymer exchange membrane fuel cells and electrochemical compressors. The electrolyte membrane is surrounded by a plastic spacer that closely matches the thickness of the membrane. A thin plastic film is bonded with an adhesive layer to both sides of the two elements, bridging the gap between the spacer and membrane. The resulting composite membrane retains the properties of conventional ion exchange membranes in its electochemically active region while benefiting from the mechanical properties of plastic laminates in the surrounding frame area. The adhesive layer bonds the assembly together and provides a gas-tight seal around the edge of the membrane. Porous electrodes with plastic frames are bonded to the composite membrane, allowing for the construction of a rigid cell frame that matches the thickness of the membrane electrode package. This structural strength simplifies the sealing of the cell.
