Cartridge for fuel cell, has tank containing source liquid oxygen compound that is decomposed, in presence of catalyst, and transfer unit provided for selective transfer of water from reaction chamber towards another tank

摘要

The cartridge (19) has a tank (20) containing a source liquid oxygen compound i.e. hydrogen peroxide, that is decomposed, in the presence of a catalyst (28) e.g. metal, to form oxygen and water. A reaction chamber (21) containing the catalyst (28) is connected to the tank via an inlet (26). Another tank (22) contains a source hydrogen material that reacts in the presence of water to form hydrogen. A transfer unit is provided for selective transfer of water from the reaction chamber towards the tank (22). A pressurization system (24) pressurizes the source liquid oxygen compound. The source hydrogen material comprises a material selected from a group consisting of hydrides, lithium, sodium, potassium, lithium and aluminum based alloy, hydrogenated porous silicon. The transfer unit is formed by a water conducting membrane e.g. polymeric membrane or a nano-porous membrane formed by a material selected from a group consisting of polymers, ceramics, metals, graphite, silicon, the silicon carbide and glasses. The catalyst is selected from a group consisting of a metal, metalloid, oxide, metallic salt. An independent claim is also included for a fuel cell comprising an enclosure seal.
