Abstract: A current producing cell has anode flow plates 22 and cathode flow plates 20. Each of the flow plates 20, 22 defines a membrane face 26, a collector face 24, and a center axis C perpendicular to the membrane face 26 and the collector face 24. Each of the collector faces 24 define a plurality of cooling channels 74, 76, 78 and a plurality of transport channels 62, 64. The cooling channels 74, 76, 78 of the cathode flow plates 20 extend radially relative to the center axis C thereof to overlap the transport channels 62, 64 of the anode flow plates 22.

Abstract: The invention relates to electrical power conversion and more specifically to a high power direct current-to-direct current (DC-DC) power converter. The DC-DC converter includes a plurality of input ports for receiving a plurality of inputs, each having current, voltage, and power, which can be selectively configured by a user. The DC-DC converter further includes a plurality of output channels for outputting current, voltage, and power, which may be selectively configured by a user. By allowing a user to configure both the inputs and outputs, the DC-DC converter may be utilized with wide variation of power conversion applications.

Abstract: The flow plate (20) defines stems (76), branches (78), and sub-branches (80) for moving fluid between each of the openings (34, 36) and the active area (42). The openings (34, 36) are trifurcated into two branches (78) and one stem (76) for providing flow of fluid through each of the stems (76) equal to the combined flow through co-diverging of the branches (78). The stems (76) have a minimal cross-sectional flow area less than the combined minimal cross-sectional flow area of the co-diverging of the branches (78). The stems (76) are bifurcated into two branches (78). The branches (78) have a uniform branch width (WB) and are bifurcated into two sub-branches (80). The active area (42) includes manifolds (46, 48) and active channels (50, 52) extending therebetween. Each of the sub-branches (80) is in fluid communication with one of the manifolds (46, 48).
