1. An electrochemical apparatus comprising:
a separator including a first reaction region and a second reaction region;
a first reaction layer disposed to correspond to the first reaction region;
a second reaction layer disposed to correspond to the second reaction region;
a first partition wall portion protruding from a first surface of the separator, disposed along a boundary between the first reaction layer and the second reaction layer, and including a first connecting flow path configured to connect the first reaction region and the second reaction region so that the first reaction region and the second reaction region fluidically communicate with each other through the first connecting flow path;
a first sealing member disposed at an end portion of the first partition wall portion and configured to seal a portion between the first reaction layer and the second reaction layer;
a first coupling protrusion protruding from the first sealing member; and
a first coupling groove provided in the first partition wall portion and configured to accommodate the first coupling protrusion therein.
