1. An electrochemical system comprising:
a gas-liquid separator configured to separate a reaction fluid into a gaseous reaction fluid and a liquid reaction fluid;
a first circulation line connected to the gas-liquid separator and configured to circulate the liquid reaction fluid;
a water electrolysis stack provided in the first circulation line;
a first pump provided in the first circulation line;
a second circulation line connected to the gas-liquid separator in parallel with the first circulation line and configured to circulate the liquid reaction fluid;
a property processing unit provided in the second circulation line and configured to process properties of the liquid reaction fluid, wherein the property processing unit comprises at least one of an ion filter configured to filter out an ion from the liquid reaction fluid or a heat exchanger configured to exchange heat with the liquid reaction fluid;
a second pump provided in the second circulation line;
a supply line connected to the gas-liquid separator and configured to supply the liquid reaction fluid to the gas-liquid separator;
a nozzle connected to an outlet end of the first circulation line and configured to inject the liquid reaction fluid into the supply line along the supply line; and
an ejector disposed at an end of the nozzle.
