摘要： A sensor (116) for monitoring the lambda of a component of a reactant feed stream (86) flowing through a fuel cell stack (32). The sensor (116) comprises one or more fuel cells (94) that are sensitive to a change in lambda of a specific component of a reactant feed stream (86) flowing through the fuel cell (94). The sensitivity of the fuel cell (94) causes a voltage produced by the lambda of the specific component. The variation of the voltage output can be modeled and/or compared to empirical data to correlate the voltage output to the lambda of the specific component. Based on the lambda of the specific component, the operation of the fuel cell stack (32) can be optimized.

摘要： An electro-chemical fuel cell stack (20) having a fuel cell assembly (24) disposed between upper and lower terminal plates (56) which are disposed between upper and lower end plates (45, 58). Optionally, spacer plates (52) can be inserted between the end plates (45, 58) and the terminal plates (56).

摘要： A fuel cell stack has at least two segments of fuel cells each having reactant gas passages. Each of the cells in each segment is arranged such that the reactant gas passages of each cell are in parallel with each other cell. Flow of fuel cell fluids, normally in a gaseous state on the anode and cathode side of each cell, is in a gravity assisted downward direction. Gravity assisted flow directs water formed in each cell to lower removal points of the stack segments. Each pair of segments is separated by a separator segment having a separator channel, the separator segment forming an integral unit of the stack. Each separator channel redirects the entire flow of each fluid within the stack from the bottom of an upstream segment to the top of a next or downstream segment, without reacting the fluid, controlling relative humidity between stack segments.
