    摘要： In a method of operating a fuel cell, a voltage difference between voltages of a first unit cell and a second unit cell is detected. Whether the voltage difference is out of a predetermined range is determined. If the voltage difference is determined to be out of the predetermined range, humidity of a first reactant gas before being supplied to a first reactant gas passage is adjusted or humidity of a second reactant gas before being supplied to a second reactant gas passage is adjusted. The first reactant gas passage is provided in a first separator. The first reactant gas is to be supplied to one of first electrodes through the first reactant gas passage. The second reactant gas is to be supplied to another of the first electrodes through the second reactant gas passage.

    摘要： A spot welding method using a welding apparatus includes supplying a pulse-shaped welding current to a workpiece, the pulse-shaped welding current being generated when a welding power circuit alternately repeats power distribution control and a power distribution pause over a plurality of cycles, and maintaining, under the power distribution control, the welding current within a set peak current range in a peak holding section. A spatter detection method includes: a step of acquiring an average value of voltage detection values Vpv detected by a voltage sensor in the peak holding section for each of the cycles; and a step of determining whether or not the spatter occurs, based on a difference value between an average value of the voltage detection values Vpv in the peak holding section for an N-th cycle and an average value of the voltage detection values Vpv in the peak holding section for an (N−1)-th cycle.

    摘要： A spot welding method includes supplying a welding current having a pulse-shaped waveform to a workpiece by alternately executing a step of maintaining the welding current within a set peak current range and a step of decreasing the welding current from the peak current range toward a bottom current and then increasing the welding current toward the peak current range when an effective value of the welding current reaches a set target range for a plurality of cycles. The spatter detection method includes measuring a pulse width IW(1), IW(2), . . . in each cycle of the pulse-shaped waveform and detecting the occurrence of spatter when a pulse width difference D(M)=IW(M)−IW(M−1) between a pulse width IW(M) in a target cycle (M-th cycle) and a pulse width IW(M−1) in a cycle immediately before the target cycle exceeds a width threshold value Dth.

    摘要： A fuel cell includes sensors. Each sensor includes: a sensor portion provided on at least one of separators, a frame member, and an electrolyte membrane; and a wiring portion connected to the sensor portion and extending to an outer peripheral portion of one of the separators or an outer peripheral portion of a membrane electrode assembly. The sensor further includes a base insulating film covering a sensor arrangement region; wiring patterns laminated on the base insulating film; and a covering insulating film covering the wiring patterns and portions of the base insulating film not covered with the wiring patterns.
