A method for manufacturing an electrochemical device includes the following steps: a step of preparing a positive electrode, the positive electrode including a first current collector and a positive electrode layer containing a conductive polymer; a step of preparing a negative electrode, the negative electrode including a second current collector and a negative electrode layer; and a step of sealing the positive electrode, the negative electrode, and an electrolytic solution in an exterior body. The step of preparing the positive electrode includes a step of holding the positive electrode in depressurized atmosphere and then introducing gas containing COas a primary component into the depressurized atmosphere.

Provided is a fuel cell catalyst layer including: a fibrous carbon material; catalyst particles; a particulate carbon material; and a proton-conductive resin, wherein a region A including at least the fibrous carbon material in a state of an agglomerated body and a region B including at least the catalyst particles, the particulate carbon material, and the proton-conductive resin are formed, the region A being disposed in an island form in the region B.

Fuel cell catalyst layer, membrane electrode assembly, and fuel cell

A capacitor electrode includes a conductive base member and an electrode part electrically connected to the base member. The electrode part contains carbon particles of a first carbon material capable of adsorbing and desorbing ions. The electrode part further contains voids including first voids with diameters of not less than 0.2 &#x3bc;m and not more than 1.0 &#x3bc;m, and second voids with diameters of not less than 0.05 &#x3bc;m and less than 0.2 &#x3bc;m. The value of (V&#xd7;V)/(V&#xd7;M) is greater than 0.022, where Vis the sum of the volumes of the first voids, Vis the sum of the volumes of the second voids, and M is the volume of the electrode part per unit weight of the electrode part.
