摘要： Aspects of some embodiments of the present invention provide flow field plates that have been designed to potentially reduce the unit cost of each flow field plate employed in an electrochemical cell stack. Thus, for some embodiments of the present invention an electrochemical cell includes a number of flow field plates each having a number of manifold apertures that all have the same area. A first one of the manifold apertures is used for a first process gas/fluid and a second one of the manifold apertures is used for a second process gas/fluid. The manifold apertures on the flow field plates align to form elongate channels that extend through the electrochemical cell as described in more detail herein.

摘要： A fuel cell stack comprising a plurality of fuel cells, each having an anode flow field plate, a cathode flow field plate and a membrane electrode assembly disposed between the flow field plates. The anode and cathode flow field plates have primary channels and ribs separating the primary channels. At least a portion of the anode and cathode primary channels are disposed directly opposite one another with a membrane exchange assembly therebetween and with at least some of the ribs on the anode and cathode flow field plates located directly opposite one another to sandwich the membrane exchange assembly therebetween. The flow field plates can also have inlet distribution and outlet collection channels.

摘要： Aspects of some embodiments of the present invention provide flow field plates that have been designed to include a flow field for uniformly distributing both a process gas/fluid and heat produced by an electrochemical reaction involving the process gas/fluid over an area covered by the flow field. Thus, for some embodiments of the present invention, in order to achieve a substantially uniform heat distribution and, possibly, in turn a substantially uniform reaction rate over the flow field, the process gas/fluid within each of the flow channels is preferably subjected to substantially the same heat exchange history as the process gas/fluid in any of the other flow channels. In some embodiments of the invention, this is accomplished by making all of the flow channels substantially the same total length.

摘要： Typically a seal is arranged around each coolant manifold aperture on each plate included in an electrochemical cell stack. However, each coolant seal is susceptible to failure. Coolant leakage from a failed coolant seal around a coolant manifold aperture on a MEA sheet can be extremely harmful because, in many cases, the coolant is corrosive to the electrolyte layer included on the MEA sheet. By contrast, in some embodiments of the invention, coolant manifold apertures are not included on MEA sheets/sheets in order to further isolate respective the electrolyte layers from coolant flowing through an electrochemical cell stack during operation. Further, in some very specific embodiments seals provided around respective coolant manifolds on corresponding anode and cathode flow field plates are made thicker, than in other areas around the corresponding anode and cathode flow field plates, to accommodate and fill the extra space left over by the absence of coolant manifold apertures and material there around on the MEA sheets.
