  • Apparatus for adjusting the humidity of gas to a constant value
    Patent number: 4406843
    Abstract: The humidity of a gas is adjusted by passing the gas through a plurality of compartments or chambers within a closed container containing the saturated aqueous solution of a salt thereby imparting a prescribed value of humidity to the gas. A plurality of partition walls are disposed at fixed intervals within the closed container defining a plurality of chambers having upper and lower interior portions and having openings formed therein alternately open into the upper and lower portions of the chambers.

  • Method for conversion of chemical energy to electric energy
    Patent number: 4380575
    Abstract: In the conversion of chemical energy into electric energy by the electrochemical reaction of a gaseous anodic reactant and a gaseous cathodic reactant through the medium of a heteropoly acid solid electrolyte, the life of the solid electrolyte is notably increased by passing each reactant through pools of a saturated aqueous solution of a specific salt bordering on closed empty spaces thereby allowing the reactants to acquire prescribed humidities prior to the contact thereof with the anode and cathode.
