Abstract

The present invention relates to a process and an electrochemical cell which produces hydrogen gas and a fuel cell which is powered by the hydrogen gas. The electrochemical cell converts hydrogen halide, such as anhydrous or aqueous hydrogen chloride, to either dry or wet chloride gas, respectively. The fuel cell generates energy in the form of direct current which can be used for a variety of purposes, which can include powering the electrochemical cell which produces the hydrogen gas.
