Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An illustrative example fuel cell device includes a cell stack assembly of a plurality of fuel cells that each include an anode and a cathode. A pressure plate is situated near one end of the cell stack assembly. A spacer between the end of the cell stack assembly and the pressure plate has a length, a width, and a height. The height of the spacer defines a spacing between the pressure plate and the end of the cell stack assembly. The spacer has a plurality of ribs that define at least two fluid reservoirs. At least one of the ribs separates the fluid reservoirs so that fluid in one of the reservoirs is isolated from fluid in the other.

Abstract: An illustrated example method of making a porous carbon composite includes mixing a carbon-based material, a binder and pore former particles to establish a mixture. The mixture is placed into a mold where it is subjected to pressure at an ambient temperature to form a compacted body. Subsequently, the compacted body is heated to a temperature that causes at least partial removal of the pore former particles to establish pores in place of at least some of the pore former particles.

Abstract: 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.
