Hydrogen membrane separator
The present application is directed to a hydrophobic membrane assembly ( 28 ) used within a gas-generating apparatus. Hydrogen is separated from the reaction solution by passing through a hydrophobic membrane assembly ( 28 ) having a hydrophobic lattice like member ( 36 ) disposed within a hydrogen output composite ( 32 ) further enhancing the ability of the hydrogen output composite's ability to separate out hydrogen gas and prolonging its useful life.
