    Abstract: The invention relates to bipolar plates for electrochemical fuel cell assemblies, and in particular to configurations of bipolar plates allowing for multiple fluid flow channels for the passage of anode, cathode and coolant fluids. Embodiments disclosed include a bipolar plate (10) for an electrochemical fuel cell assembly, comprising: a first plurality of fluid flow channels (13) extending across a first face of the bipolar plate between first inlet and outlet ports (18a, 18b) at opposing ends of the bipolar plate; a second plurality of fluid flow channels (22) extending across a second opposing face of the bipolar plate between second inlet and outlet ports (21a, 21b) at opposing ends of the bipolar plate; and a third plurality of fluid flow channels (14) extending between third inlet and outlet ports (19a, 19b) at opposing ends of the bipolar plate, the third plurality of fluid flow channels provided between first and second corrugated plates (11, 12) forming the first and second opposing faces of the bipolar plate, wherein the first, second and third fluid flow channels are coplanar.

    Abstract: A fluid flow plate for an electrochemical assembly has a plurality of first fluid flow channels extending across an active area of the flow plate to define a first fluid flow field of the fluid flow plate and a plurality of second fluid flow channels extending across the active area of the flow plate to define a second fluid flow field of the fluid flow plate. An array of first fluid transfer points is disposed along an edge of the first fluid flow field for communicating fluid into or out of the first fluid flow channels. An array of second fluid transfer points is disposed along an edge of the second fluid flow field for communicating fluid into or out of the second fluid flow channels. A first fluid gallery a first peripheral edge portion bounded by the array of first fluid transfer points and has a second peripheral edge portion forming a first fluid communication edge of the fluid flow plate. A second fluid gallery has a first peripheral edge portion bounded by the array of second fluid transfer points and has a second peripheral edge portion forming a second fluid communication edge of the fluid flow plate. The first fluid gallery and the second fluid gallery are shaped such that the combined lengths of the second peripheral edge portions are longer than the first peripheral edge portion of the second fluid gallery or the first fluid gallery. Increasing the lengths of the second peripheral edge portions of each gallery to the maximum possible length compared to the length of fluid transfer points (i.e. width of the active flow field area) optimizes fluid distribution into the channels of the flow plate.

    Abstract: A bipolar fluid flow plate for an electrochemical assembly comprises a plurality of first fluid flow channels extending across a face of the flow plate to define a first fluid flow field of the fluid flow plate and a plurality of second fluid flow channels extending across a face of the flow plate to define a second fluid flow field of the fluid flow plate. The pluralities of first fluid flow channels and second fluid flow channels both occupying a common channel plane. An array of first fluid transfer points is disposed along an edge of the first fluid flow field for communicating fluid into or out of the first fluid flow channels. An array of second fluid transfer points is disposed along an edge of the second fluid flow field for communicating fluid into or out of the second fluid flow channels. A first fluid gallery has a first peripheral edge portion bounded by the array of first fluid transfer points and has a second peripheral edge portion forming a first fluid communication edge of the fluid flow plate. A second fluid gallery has a first peripheral edge portion bounded by the array of second fluid transfer points and has a second peripheral edge portion forming a second fluid communication edge of the fluid flow plate. The first fluid gallery occupies a first gallery plane and the second fluid gallery occupies a second gallery plane different from the first gallery plane. Both the first gallery plane and the second gallery plane are disposed within the channel plane. This structure enables the feeding of multiple different fluids into coplanar channels across the full width of a flow field.

    Abstract: A fuel cell (FC) system operating as its own hydrogen leak detector. The system including at least one cathode and cathode conduit for passage of oxidant to the cathode and a housing containing one or more FCs and defining a plenum around the FC. A ventilation system forces air from the plenum into the cathode conduit and a control system monitors the FC voltage and detects a drop in voltage attributable to hydrogen in the cathode conduit. A control system may include actual cell voltage monitoring of the FC or of one or more cells in the FC stack and a processor for receiving inputs indicative of the operation of the FC or FC stack and/or to determine an expected voltage of FC(s) being monitored and whether the difference between the actual and expected voltage(s) exceeds a predetermined threshold indicative of a predetermined level of hydrogen in the cathode conduit.
