摘要： PROBLEM TO BE SOLVED: To provide a fuel cell equipped with an electrode in a distribution state in which a distribution state of electrolyte is as aimed at in a thickness direction. SOLUTION: The method for manufacturing the fuel cell includes a first process for measuring each of a plurality of frequency AC impedances in a plurality of regions of a first membrane electrode assembly equipped with a first electrode containing a first electrolyte manufactured under given manufacturing conditions, a second process for estimating a distribution of the first electrolyte in a thickness direction of the first electrode based on an AC impedance of each frequency measured respectively to each regions in the first membrane electrode assembly, and a third process, in case, among regions in the first membrane electrode assembly, a first region which is not the desired distribution aimed at the distribution estimate result of the first electrolyte in the second process exists, manufacturing a second electrode containing second electrolyte by adjusting manufacturing conditions to a region corresponding to the first region based on the distribution estimate result of the first region.

摘要： The invention provides an apparatus for estimating fuel-cell hydrogen concentration and a fuel cell system which exploit the correlation between impedance semicircles and hydrogen concentrations to estimate fuel-cell hydrogen concentration. A fuel cell system includes a fuel cell 2, an impedance measuring instrument 3, and a control device 5. The control device 5 is connected to the impedance measuring instrument 3. The impedance measuring instrument 3 measures the impedance of the fuel cell 2 according to the AC impedance method. The control device 5 stores in advance a reference value corresponding to a reference hydrogen concentration. The control device 5 compares the real part Z' of impedance acquired via the impedance measuring instrument 3 against the reference value. When Z' is equal to or greater than the reference value, the control device 5 estimates the hydrogen concentration of the fuel cell 2 to be equal to or less than the reference hydrogen concentration.
