Abstract

A sodium chloride electrolysis cell ( 9 ) receives a portion of its electrical power ( 47, 48: 50, 51 ) from a phosphoric acid fuel cell ( 44 ) which receives fuel at its anode inlet ( 43 ) from a water cooled catalytic reactor ( 26 ) that converts oxygen in the byproduct output ( 19 ) of the sodium chlorate electrolysis cell to hydrogen and water. A utility grid ( 53 ) may provide through a converter ( 55 ) power to support the electrochemical process in the sodium chlorate electrolysis cell. Temperature of the water cooled catalytic reactor is determined by the vaporization of pressurized hot water, the pressure of which may be adjusted by a controller ( 36 ) and a valve ( 38 ) in response to temperature ( 40 ).

Claims (7)

1. Apparatus, comprising:

a sodium chlorate electrolysis cell ( 9 ) configured to provide at a product output ( 14 ) sodium chlorate, and to provide at a byproduct output ( 19 ) a gas including hydrogen, oxygen, chlorine and organics;

characterized by:

a phosphoric acid fuel cell ( 44 ) having an anode inlet ( 43 ) and providing electrical power ( 47 , 48 : 50 , 51 ) to the sodium chlorate electrolysis cell; and

the byproduct output ( 19 ) of said sodium chlorate electrolysis cell ( 9 ) is provided ( 21 - 24 ) to a water cooled catalytic reactor ( 26 ) which converts hydrogen and oxygen to water and having an output ( 41 ) which is applied ( 42 ) to the anode inlet ( 43 ) of the phosphoric acid fuel cell ( 44 ).

2. Apparatus according to claim 1 characterized in that the water cooled catalytic reactor ( 26 ) is cooled by pressurized hot water in a conduit ( 30 ) from a pressurized hot water source ( 32 ), having a pressure which is such that increase in temperature within said water cooled catalytic reactor causes the pressurized hot water to boil, thereby cooling the water cooled catalytic reactor.

3. Apparatus according to claim 1 characterized in that a pressurized hot water source ( 32 ) is configured to provide to the water cooled catalytic reactor ( 26 ), pressurized hot water in a conduit ( 30 ) having temperature and pressure which are such that increase in temperature within said water cooled catalytic reactor causes the pressurized hot water to boil, thereby cooling the water cooled catalytic reactor.
