摘要： PROBLEM TO BE SOLVED: To provide a novel catalyst layer which exhibits high effectiveness of preventing reduction in power generation capacity.SOLUTION: In a cathode 22 as an electrode catalyst layer, Pt carrying carbon particles 50 and Pt non-carrying carbon particles 51 are mixed in a state coated, respectively, with a first electrolyte resin 71 and a second electrolyte resin 72. Since the second electrolyte resin 72 with which the Pt non-carrying carbon particles 51 are coated has an ion exchange group equivalent smaller than that of the first electrolyte resin 71 with which the Pt carrying carbon particles 50 are coated, the second electrolyte resin 72 has a water retentivity higher than that of the first electrolyte resin 71 with which the Pt carrying carbon particles 50 are coated.

When passing through the bottomed groove portions 30, the hydrogen gas takes away a water component which has intruded into the groove portions 30, to the downstream side.

Strain generated in the design liner when impact force acts is analyzed. When strain εa in the axial direction is larger than strain εb in the peripheral direction, a Th lower limit value being a lower limit value of the whole thickness of the helical winding layer capable of holding the tank shape by a high pressure tank having the design liner is calculated. A Tf/Th design value being the ratio of the whole thickness Tf of the hoop winding layer in the design fiber reinforced resin layer group to the whole thickness Th of the helical winding layer is determined. At this time, the TH in the Tf/Th design value is set as the Th lower limit value.
