Apparatus and method for installing an electrochemical cell stack

A method for assembling an electrochemical cell stack, the method having the steps:

• assembling a first stack component (140), which has a first adjustment opening (115), on an electrochemical substack through cooperation between the first adjustment opening (115) and a first adjustment device (110) defining a longitudinal axis that extends in a longitudinal direction;
• and
• repositioning the first adjustment device (110) in the longitudinal direction for locally adjusted assembly of a second stack component (140), which has a corresponding first adjustment opening (115) for locally adjusted assembly,
• wherein the first and the second stack component (140) are assembled with aid of a total adjustment device (130), the total adjustment device (130) engages and aligns an outer perimeter of the first and the second stack components (140), while the first adjustment device (110) locally adjusts the first and the second stack component (140),
• wherein the first adjustment device (110) only engages stack components of a plurality of stack components that are arranged in an upper part of the electrochemical substack for locally adjusted assembly, and does not engage stack components of the plurality of stack components that are arranged in a lower part of the electrochemical substack.
