NOVELTY - The apparatus for processing a hydrogen gas stream generated from a chemical hydride, comprises a housing comprising a heat- and pressure-resistant material and an internal chamber to receive the hydrogen gas stream, a condensing media disposed within the internal chamber, a coalescer (406) element disposed within the internal chamber to receive the hydrogen gas stream as the hydrogen gas stream exits the condensing media, an outlet port disposed in the housing in fluid communication with the internal chamber, and a condensor (404). The condensing media has passages to engage liquid water.    USE - The apparatus is useful for processing a hydrogen gas stream generated from a chemical hydride such as lithium hydride, lithium tetrahydridoaluminate, lithium tetrahydridoborate, sodium hydride, sodium tetrahydridoaluminate and sodium tetrahydridoborate, where hydrogen gas stream is useful in a proton exchange membrane fuel cell.    ADVANTAGE - The apparatus is capable of easily and rapidly processing a hydrogen gas stream generated from a chemical hydride without extra space and weight thus effectively avoiding impurities such as salts, acids, organic compounds and the like present in the stream and providing improved gravimetric and volumetric energy density to the fuel cell.    DETAILED DESCRIPTION - The apparatus for processing a hydrogen gas stream generated from a chemical hydride, comprises a housing comprising a heat- and pressure-resistant material and an internal chamber to receive the hydrogen gas stream, a condensing media disposed within the internal chamber, a coalescer (406) element disposed within the internal chamber to receive the hydrogen gas stream as the hydrogen gas stream exits the condensing media, an outlet port disposed in the housing in fluid communication with the internal chamber, and a condensor (404). The condensing media has passages to engage liquid water entrained in the hydrogen gas stream and to remove the entrained liquid water from the hydrogen gas stream. The liquid water is formed as the hydrogen gas stream cools. The coalescer element removes liquid water formed in the hydrogen gas stream. The outlet port is configured to receive the hydrogen gas stream and to deliver the hydrogen gas stream in outside of the housing. The condenser comprises a channel defined by a wall that absorbs heat from the hydrogen gas stream, and a corrosion-resistant material with a thermal conductivity of greater than 5 W/mK. The channel delivers the hydrogen gas stream to an internal chamber in upstream of the condensing media. A cooling module is arranged for conducting heat from the condenser to a surrounding environment, and comprises a fluid circulation device that circulates a fluid in contact with the wall. A mechanical filtration element is disposed within the internal chamber to receive the hydrogen gas stream, and comprises filtration passages to collect particulate matter larger than a selected diameter from the hydrogen gas stream. A pre-filter (402) is arranged for receiving the hydrogen gas stream before it enters into the condensing media, and comprises filtration passages comprising a material that collects solid and gaseous contaminants from the hydrogen gas stream. The condensing media, the mechanical filtration element, the pre-filter, and the coalescer element are located within a chemical hydride fuel cartridge. The hydrogen gas stream has a temperature within an operating temperature threshold of a fuel cell configured to consume the hydrogen gas stream and a relative humidity of less than or equal to 100%. An organic filter (408) is arranged for receiving the hydrogen gas stream from the coalescer element and captures one or more of organic vapor contamination and inorganic vapor contamination from the hydrogen gas stream. A hydrogen-selective membrane is arranged for receiving the hydrogen gas stream in upstream of the outlet port. INDEPENDENT CLAIMS are included for:    (1) a method for processing a hydrogen gas stream generated from a chemical hydride; and    (2) a system to generate electric power from a chemical hydride.
