Abstract: A hybrid Rankine cycle system comprises a boiler in which water steam is generated, a steam turbine which is worked by the water steam from the boiler to drive a generator to obtain an electric power, an absorber condenser for introducing thereinto strong absorbent solution to absorb the water steam from the steam turbine to produce weak absorbent solution, and a pump for delivering the weak absorbent solution from the absorber condenser to the boiler. The weak absorbent solution is heated in the boiler to produce the strong absorbent solution to be fed to the absorber condenser and the water steam to be fed to the steam turbine.

Abstract: A carbon monoxide-oxygen system fuel cell having overcome various drawbacks of such fuel cell and capable of using CO, as it is, as its fuel without employing any shift converters is provided, which fuel cell is provided with a diaphragm between an anode and a cathode to separate the two electrodes and characterized in using a solution containing at least a monovalent copper and a halide as a complexing agent for the copper, as the electrolytic solution for the anode, and reacting CO in the form of a carbonyl complex of the copper in the electrolytic solution.
