  • Integral hydrogen and air purifier
    Patent number: 8608836
    Abstract: A gas purifier assembly for providing first (50) and second (38) purified gas streams having an integral heater (54). The assembly can have two separate chambers for gaseous fluid flow for the purpose of purifying a gas stream of hydrogen (34), for example, and a separate distinct stream of gas such as compressed air (46). A centrally located heater heats the first chamber to effect purification of the first gas. Waste heat from the first chamber is transferred to the second chamber via conduction to effect purification of the second gas stream.
