1. A single stage process for generation of hydrogen enriched gas, the process comprising:
a) providing an ion conducting membrane between Zone-A and Zone-B of a hydrogen enriched gas generation unit;
b) routing a hydrogen source through a heat exchanger HEX 08 to Zone-A of the hydrogen enriched gas generation unit, wherein Zone-A is configured to oxidize the hydrogen source to generate hydrogen ions, and wherein the hydrogen ions generated pass through the ion conducting membrane to a catalyst layer of Zone-B;
c) maintaining a higher localized hydrogen pressure at an interface of catalyst and perforated catalyst protective sheets (PCPS) than a pressure prevailing at an interface of PCPS and microchannels in Zone-B; and
d) passing a feed gas through a heat exchanger HEX 03 to Zone B wherein feed gas and hydrogen ions are homogeneously mixed in the microchannels of Zone-B for generating the hydrogen enriched feed gas, wherein the process is an electrochemical process.
