摘要： A method and system for detecting imperfections in a membrane electrode assembly of an electrochemical fuel cell, and more particularly for detecting defects within a proton exchange membrane in a membrane electrode assembly which is optionally sandwiched between conductive diffusion media layers or between conductive diffusion layers with at least one rigid solid that is transparent to infrared radiation. A potential voltage is applied across the membrane and the presence of a defect and preferably the location of a defect is determined by monitoring variations in intensity level of infrared radiation emitted from a surface of the membrane electrode assembly.

摘要： The present invention is directed to a planar flow field design having an intake manifold and an exhaust manifold which are configured in two offset planes. A relatively short passage extends from the intake manifold through the exhaust manifold and terminates at a reactive face of a membrane electrode assembly (MEA) such that a differential flow distribution is provided from the intake manifold through the passage and across a reactive face of the MEA to the exhaust manifold.

摘要： The present invention is directed to an electrochemical fuel cell. The configuration of the fuel cell stack provides a multiple-legged current flow path therethrough. Electrically isolated zones are formed in the cells and one coupled in a serial manner. This configuration provides incremental voltage summing such that additional power converting element are not needed to match the stack output to the load.

摘要： A current sensor assembly that monitors current flow through segments of a fuel cell stack. The current sensor assembly includes a first plate including a first non-conductive substrate having a first conductive path therethrough and that is in electrical communication with a first segment of the fuel cell stack. A second plate includes a second non-conductive substrate having a second conductive path therethrough and that is in electrical communication with a second segment of the fuel cell stack. A first current sensor is operably disposed between the first plate and the second plate and facilitates a first current flow between the first conductive path and the second conductive path. The first current sensor generates a first current signal based on the first current flow.

摘要： A switch assembly for selectively enabling current flow through a segment of a fuel cell stack. The switch assembly includes a first plate including a first non-conductive substrate having a first conductive path therethrough and a second plate including a second non-conductive substrate having a second conductive path therethrough. A first switch is disposed between the first plate and the second plate and is in electrical communication with the first conductive path and the second conductive path. The first switch is operable in an open mode to prohibit current flow between the first conductive path and the second conductive path. The first switch is operable in a closed mode to enable current flow between the first conductive path and the second conductive path.
