Patent ID: 7674539

Claim:
An electrical current generating system comprising: a hydrogen-containing gas source comprising a reformer or partial oxidation reactor, wherein the reformer or partial oxidation reactor comprises a first burner and a second burner; at least one adsorption module that can at least partially purify the hydrogen-containing gas, wherein the adsorption module includes at least a first adsorbent and at least one second material selected from a second adsorbent, a steam reforming catalyst, or a water gas shift reaction catalyst, the first adsorbent and the second adsorbent being chemically distinct; at least one fuel cell defining an anode inlet that can receive the purified hydrogen-containing gas stream from the adsorption module; and a turbocompressor that includes an expander, wherein the first burner receives an exhaust gas from the adsorption module, the second burner receives a hydrocarbon fuel feed, and the expander receives a combustion gas from the second burner.
