초록 ▼

An improved high-efficiency electrochemical motor is disclosed that uses hydrogen gas in a gas-tight pump housing to convert electrical energy to mechanical work. The motor consists of an electrolytic membrane with pervious electrodes on both sides separated by the thickness of the electrolytic membrane such that the gas, being electrochemically reversibly active, enters into an anodic reaction on one side of the membrane where the gas molecules are converted to ions transportable through the electrolytic membrane and a cathodic reaction at the opposite electrode where the ions are reconverted to gas molecules. By applying a reversible electric current to the electrodes to transport the ions through the electrolytic membrane, the gas is pumped reversibly from one gas-tight chamber to another. A diaphragm disposed in a gas-tight motor housing moves from one motor housing partition to the other in response to an imbalance in the pressure of the gas. A novel integral pressure sensor for sensing the pressure of the gas and an integral dumping valve for rapidly resetting the diaphragm are disclosed. A controller uses the sensed pressure in controlling the magnitude and direction of the electric current that causes the gas to flow into one or the other of two gas-tight pump chambers. Convertors are disclosed for converting the gas pressure change to mechanical motion.

An electrochemical motor comprising: storage means for holding a supply of electrochemically active gas; a gas-tight pump housing; a rigidly supported electrolytic membrane having two sides disposed in said gas-tight pump housing and defining therein first and second gas-tight pump chambers; first connection means for the free flow of said gas from said storage means to said first gas-tight pump chamber; a gas-tight motor housing comprising first and second motor partitions; a diaphragm disposed in said gas-tight motor housing and defining therein a first gas-tight motor chamber with said first motor partition and a second gas-tight motor chamber with said second motor partition; said two motor partitions disposed to act as immobile diaphragm stops; at least one of said diaphragm stops being shaped to conform topographically with said diaphragm such that the displacement volume of at least one said motor chamber is substantially zero in at least one of said end of stroke positions of said diaphragm, so that said diaphragm may move from one said diaphragm stop to the other in substantially immediate response to a change in gas pressure in said first gas-tight motor chamber; second connection means for providing a free flow of said gas between said second gas-tight pump chamber and said first gas-tight motor chamber; at least one pervious electrode disposed on each said side of and in contact with said electrolytic membrane; said at least one electrode on the first said side of said electrolytic membrane being separated from one another by spaces and said at least one electrode on the second side of said electrolytic membrane being disposed to form, wtih said at least one electrode on said first side, at least one electrode pair separated by said electrolytic membrane; said gas being electrochemically reversibly active so as to enter into an anodic reaction at one side of said at least one electrode pair where the gas molecules are converted to ions transportable through said electrolytic membrane and a cathodic reaction at the opposite side of said at least one electrode pair where said ions are reconverted to gas molecules; means for providing a reversible electric current to said at least one electrode pair, said current acting to transport said ions through said electrolytic membrane whereby said gas is pumped reversibly from one said side of said electrolytic membrane to the other; pressure sensing means for sensing the pressure of said gas in at least one of said gas-tight pump chambers; control means, responsive to said pressure sensing means for varying the magnitude and direction of said electric current oc ause said gas to flow through said electrolytic membrane into one or the other of said gas-tight pump chambers; and means for converting the gas pressure change in said second gas-tight motor chamber to mechanical motion.
