Patent attributes
An alkaline water electrolysis system includes: a plurality of reaction chambers, each including a main electrode and an auxiliary electrode; a piston provided in each reaction chamber to change a volume of the reaction chamber through reciprocating motion; a drive motor; a connecting rod and a crankshaft installed to change rotational motion of the drive motor into reciprocating linear motion of the piston; a plurality of gas valves installed on an upper side of the reaction chamber to discharge hydrogen and oxygen generated in the reaction chamber through different paths, respectively; a pressure sensor installed in the reaction chamber; a controller configured to open and close the gas valves in response to a signal received from the pressure sensor; and an electrolyte supply apparatus provided to supply an electrolyte to the reaction chambers.
