At least one membrane is provided at one or more ends of the fuel cell unit. The membrane is operable to enable a flow of oxygen through the at least a portion of fuel cell unit. Further, the membrane is further operable to prevent water from flowing through at least a portion of the fuel cell. Moreover, an electrical source in operative engagement with the fuel cell unit. The fuel cell operates in a first mode to collect the hydrogen when receiving voltage from the electrical source, and further the fuel cell operates in a second mode to generate electricity using the hydrogen. The fuel cell unit is preferably stackable via a combination of conductible studs and receptacles.
US09819041B2	Mixed metallic oxides as scavengers for fluorinated ion exchange polymers A mixed oxide of Si and at least one metal M comprising inorganic groups —SO3H. The addition of the mixed oxide to fluorinated polymers containing sulfonic acid functional groups increases their stability towards radical degradation when used in fuel cell applications.
