Measurements of the solubility of oxygen in sulfuric acid, phosphoric acid, and potassium hydroxide are reported, together with values of the diffusivity of oxygen in potassium hydroxide solutions at 25°C. It is shown that for the electrolyte concentrations commonly employed in fuel cells the solubility and diffusivity of oxygen may each be reduced to as little as 2% of their corresponding values for pure water.
