Abstract:
This invention is an apparatus and a method for continuously generating a hydride gas of metal M1 which is substantially free of oxygen in a divided electrochemical cell. An impermeable partition or a combination of an impermeable partition and a porous diaphragm can be used to divide the electrochemical cell. The divided electrochemical cell has an anode chamber and a cathode chamber, wherein the cathode chamber has a cathode comprising metal M1, the anode chamber has an anode capable of generating oxygen, an aqueous electrolyte solution comprising a metal hydroxide M2OH partially filling the divided electrochemical cell. Hydride gas generated in the cathode chamber and oxygen generated in the anode chamber are removed through independent outlets.
Abstract:
Fluid flow valve assembly comprising a valve body having an external port and an inlet end having at least a first port, a second port, and a third port; a first valve disposed within the valve body and adapted to control fluid flow between the first and second ports; and a second valve disposed within the valve body and adapted to control fluid flow between the third port and the external port.
