Abstract: A method for testing a fuel cell stack includes providing a fluid, such as an ammonia-containing fluid, in a first reactant flow path in a first portion of the fuel cell stack, detecting the presence of the fluid using a detector, such as an ammonia detector, positioned within or adjacent to a second portion of the fuel cell stack that is separated from the first portion of the fuel cell stack and determining the presence of a defect in the stack based on detecting the presence of the fluid. Further embodiments relate to testing a fuel cell stack using a microphone that detects an audio signal indicative of a stack defect.

Abstract: Various embodiments include interconnects and/or end plates having features for reducing stress in a fuel cell stack. In embodiments, an interconnect/end plate may have a window seal area that is recessed relative to the flow field to indirectly reduce stress induced by an interface seal. Other features may include a thicker protective coating and/or larger uncoated area of an end plate, providing a recessed portion on an end plate for an interface seal, and/or recessing the fuel hole region of an interconnect relative to the flow field to reduce stress on the fuel cell. Further embodiments include providing intermittent seal support to minimize asymmetric seal loading and/or a non-circular seal configuration to reduce stress around the fuel hole of a fuel cell.

Abstract: A method of controlling a fuel cell system includes applying alternating current (AC) signals to an individual fuel cell. The AC signals have a plurality of different frequencies. A voltage across the individual fuel cell is determined at each of the plurality of different frequencies. An impedance characteristic of the individual fuel cell is determined based at least in part on the voltage across the individual fuel cell at each of the plurality of different frequencies. The individual fuel cell is controlled based at least in part on the impedance characteristic.
