1. An electrochemical cell, comprising:
a first cell comprising a first power generation element and a first inner container, the first inner container fully enclosing the first power generation element, and a surface of the first inner container being provided with a convexity that has (i) a curved surface and/or (ii) a flat surface;
a second cell comprising a second power generation element and a second inner container, the second inner container fully enclosing the second power generation element, and a surface of the second inner container being provided with a concavity that has a curved surface and/or a flat surface;
an outer container which fully encloses the first cell and the second cell; and
a fit portion in which the convexity is fitted in the concavity.
