    摘要: A frameless bipolar cell stack architecture with either internal manifolds of circulation of electrolyte solutions “in parallel” through all respective cell compartments or internal ducting adapted to provide for “serial” flow paths of the electrolyte solutions in succession through all respective cell compartments of the stack, does not employ any plastic frame and employs substantially planar bipolar electrical interconnects (I) of substantially homogeneous electrical conductivity with a perimeter that super-imposes to the perimeter of any other element of the stack. Whenever useful for the particular application, the planar interconnects may have a protruding “lug portion” that projects beyond the outer perimeter side of the other stacked elements, providing an externally contactable area sufficiently large for the power (current rating) of an electrical tap, at an intermediate voltage relative to the voltage difference between the end terminals of the stack, connectable to an external circuit.

    摘要: A fuel cell membrane electrode assembly (MEA) comprising first and second gas diffusion layers and an ion exchange membrane disposed between the diffusion layers. Each diffusion layer includes an inner surface facing the membrane, an outer surface opposite the inner surface, and a side surface defining a perimeter of the diffusion layers. An outboard region extends about the diffusion layers at the perimeter. The outboard region surrounds an inboard region. The outboard region has a low density region proximate to the side surface and a high density region between the low density region and the inboard portion. A seal is mounted at the low density region. The high density region prevents portions of the seal from entering the inboard region thereby damaging the MEA. The seal includes a first rim having a smaller radius than a second rim. The smaller radius allows the seal to fit between adjacent support plates and increases the durability of the seal.

    摘要: The invention relates to the field of electrochemical cells and fuel cells, more specifically to polymer-electrolyte-membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC). A multi-layer membrane-electrode-assembly (ML-MEA) comprising two electrically conductive bipolar plates and a membrane-electrode-assembly (MEA) bonded together by means of an electrically insulating adhesive material is disclosed. The adhesive material, preferably a polyurethane-based system, is in direct contact with the protective film layers attached to front side and the back side of the MEA, thus contamination of the ionomer membrane and/or the electrode layers with adhesive components is avoided. Multi-layer MEAs with improved long term stability and life time are obtained. The products are used for the manufacture of low temperature PEMFC and DMFC stacks.

    摘要: A composite seal having a multilayer elastomeric construction and method for constructing the same is provided. More specifically, the present invention provides a composite seal comprised of a low-durometer elastomer compliant layer coated with, or alternatively encapsulated by, a thin protective layer for securely sealing a bipolar plate and a membrane electrode assembly of a fuel cell. The elastomer compliant layer is preferably a silicone constituent and the thin coat protective layer is preferably a fluoroelastomer or fluoropolymer constituent suitable for bonding to the elastomer compliant layer. The foregoing layers constructing the composite seal are preferably deposited directly onto the aforementioned fuel cell components along a predetermined periphery. The resulting composite seal is thin in construction, resistive to undesired chemical and thermal reactions and provides the necessary compressive compliance without undue stress on the fuel cell assembly.
