    摘要： A fuel cell comprises a membrane electrode assembly configured such that electrode catalyst layers are formed on respective surfaces of an electrolyte membrane; gas diffusion layers placed on respective surfaces of the membrane electrode assembly; and a frame placed around periphery of the membrane electrode assembly. The membrane electrode assembly has a protruding portion that is configured by protruding outside of the gas diffusion layer in a state that the membrane electrode assembly is combined with the gas diffusion layers. The frame has an engagement portion that is configured to engage with the protruding portion. An adhesive layer is formed from an ultraviolet curable adhesive between the protruding portion and the engagement portion.

    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.
