To provide an electrochemical device capable of improving gas sealability.SOLUTION: An electrochemical device includes: a separator in which a hydrogen electrode gas flow passage through which hydrogen electrode gas flows and an oxygen electrode gas flow passage through which oxygen electrode gas flows are formed; and an electrochemical cell that is provided on the separator and has an electrolyte film interposed between a hydrogen electrode and an oxygen electrode. Hydrogen electrode gas passes through the hydrogen electrode and oxygen electrode gas passes through the oxygen electrode. The electrochemical device has: a hydrogen electrode gas pipeline directly coupled to the separator so as to communicate with the hydrogen electrode gas flow passage; and an oxygen electrode gas pipeline directly coupled to the separator so as to communicate with the oxygen electrode gas flow passage.SELECTED DRAWING: Figure 1B 【課題】ガスのシール性を向上可能な電気化学装置を提供する。【解決手段】実施形態の電気化学装置は、水素極ガスが流れる水素極ガス流路および酸素極ガスが流れる酸素極ガス流路が形成されているセパレータと、セパレータに設けられ、水素極と酸素極との間に電解質膜が介在している電気化学セルとを有し、水素極ガスが水素極を通過し、酸素極ガスが酸素極を通過する。電気化学装置は、水素極ガス流路に連通するように、セパレータに直接的に連結されている水素極ガス配管と、酸素極ガス流路に連通するように、セパレータに直接的に連結されている酸素極ガス配管とを有する。【選択図】図１Ｂ
