1. An electrochemical cell comprising:
an electrolyte membrane;
an anode current collector laminated on one surface of the electrolyte membrane;
a cathode current collector laminated on another surface of the electrolyte membrane; and
a supply flow path that is disposed on a surface of the anode current collector opposite to a surface thereof facing the electrolyte membrane and through which a fluid to be supplied to the anode current collector flows,
wherein the anode current collector consists of an inner portion in which a first hole is formed, and an outer portion in which a second hole is formed, the first hole having a cross-sectional area that increases toward the supply flow path, the second hole having a cross-sectional area that increases toward the electrolyte membrane,
the outer portion is located outside the inner portion and adjacent to the inner portion and surrounds the inner portion from outside, and
the inner portion is devoid of the second hole and the outer portion is devoid of the first hole.
