摘要： An illustrative example fuel cell assembly includes a plurality of fuel cells arranged in a stack including a first end fuel cell near a first end of the stack and a second end fuel cell near a second end of the stack. Each of the fuel cells includes a matrix containing an electrolyte, an anode and a cathode on opposite sides of the matrix, and respective flow fields adjacent the anode and the cathode. An electrolyte supply associated with the anode flow field of the first end fuel cell includes a porous material containing electrolyte. An electrolyte collector associated with the cathode flow field of the second end fuel cell includes a porous material configured to collect electrolyte from at least the cathode of the second end fuel cell.

摘要： An illustrative example fuel cell power plant includes a cell stack assembly having a plurality of fuel cells configured to generate electricity based on an electrochemical reaction. The power plant includes a capacitor, a plurality of inverters, and at least one controller that is configured to control the plurality of inverters in a first mode and a second mode. The first mode includes the cell stack assembly associated with at least one of the inverters. A cell stack assembly and the associated inverter provide real power to a load external to the fuel cell power plant in the first mode. The second mode includes at least a second one of the inverters associated with the capacitor. The capacitor and the second one of the inverters selectively provide reactive power to or receive reactive power from a grid external to the fuel cell power plant in the second mode.

摘要： An illustrative example fuel cell component includes a plate with a plurality of flow channels in at least one side of the plate. Each of the flow channels has a length between an inlet and an outlet. Each of the flow channels has a width and a depth, which are transverse to the length. At least some of the flow channels include a portion near the inlet and the width or the depth of the portion is greater than the width or depth along a majority of the length of those flow channels.

摘要： An illustrative example fuel cell power plant includes a cell stack assembly, a single stage convertor configured to couple the cell stack assembly to a power network, and a controller that is configured to determine whether the fuel cell power plant has a DC voltage brownout condition during an islanded mode of operation. The controller dynamically adjusts the frequency droop gain of the power plant using an offset while satisfying at least three criteria of a set of criteria consisting of (i) avoiding overloading other fuel cell power plants of the power network, (ii) avoiding exceeding a maximum load step-up capability of the power network, (iii) avoiding exceeding a maximum load step-up capability of the fuel cell power plant, (iv) maintaining a system frequency within an acceptable frequency range, and (v) avoiding repeating the DC voltage brownout condition.

摘要： A cloud tower (11) receives microscopic particles (18) impelled by an inert gas (17) for deposition on a porous substrate (29) having vacuum (34) disposed on opposite side. To alter the size and/or shape of the deposition field without changing the entire tower structure, a pair of flaps (43, 44) are hinged (47, 48) on one side or on a pair of opposed sides of the cloud primary tower. Another embodiment places selectable tower inserts (36, 38) within the primary tower structure, fitting therein and sealing thereto.

摘要： According to an example embodiment, a method of making a fuel cell component includes permeating at least a portion of a component layer with a polymer. The portion of the component layer is adjacent an edge of the component layer. Some of the polymer is allowed to extend beyond the edge to thereby establish a flap beyond the edge of the component layer. A fuel cell component includes a component layer having a portion adjacent an edge of the layer that is impregnated with a polymer material and a flap of the polymer material extending beyond the edge.

摘要： A cylindrical shift converter (4) is disposed within an annular heat exchanger (28, 24) which has an outer wall (5). A plurality of spiral rods (90) create a plurality of spiral gas passages (26a) between the outer wall and a thin shell (92). The outer diameter of the thin shell is at least about 3/16 inch (about 4 mm) less than the inner diameter of an inner wall (20) of an annular hydrodesulfurizer (10), to facilitate inserting the shift converter and heat exchanger into the hydrodesulfurizer to form a unitized assembly (2). The spiral passages open into the hydrodesulfurizer.
