NOVELTY - The electrode cartridge (100) comprises an anode configured to generate electrons in an electrolyte solution, a cathode configured to generate hydrogen from the electrolyte solution by receiving the electrons at the anode, a liquid-gas separation membrane disposed to surround the anode and the cathode, a support (140) configured to support the separation membrane for preventing an expansion of the separation membrane, a frame (150) configured to support the separation membrane, an absorption layer disposed to surround the anode and the cathode, and a connection terminal (155).    USE - The electrode cartridge is useful in a hydrogen generating apparatus and a fuel cell generation system (all claimed), where the fuel cell such as polymer electrolyte membrane fuel cell and direct methanol fuel cell, is useful in portable electronic devices.    ADVANTAGE - The electrode cartridge prevents the backflow of an electrolyte solution during the generation of hydrogen and an effect of an electrolyte solution leak when moving place to place thus improving the hydrogen generating efficiency.    DETAILED DESCRIPTION - The electrode cartridge (100) comprises an anode configured to generate electrons in an electrolyte solution, a cathode configured to generate hydrogen from the electrolyte solution by receiving the electrons at the anode, a liquid-gas separation membrane disposed to surround the anode and the cathode, a support (140) configured to support the liquid-gas separation membrane for preventing an expansion of the liquid-gas separation membrane, a frame (150) configured to support the liquid-gas separation membrane for maintaining space inside the liquid-gas separation membrane, an absorption layer disposed to surround the anode and the cathode and configured to absorb the electrolyte solution carried in the hydrogen, and a connection terminal (155) electrically connected to the anode and the cathode and configured to electrically connect the anode and the cathode to an outside device. The liquid-gas separation membrane configured to separate the hydrogen from the electrolyte solution and discharge the hydrogen to the outside. The liquid-gas separation membrane comprises unit liquid-gas separation membranes (122, 124, 126), in which each of the unit liquid-gas separation membranes is supported by the frame. The support is a board and an opening formed on the board to allow the hydrogen to pass. The liquid-gas separation membranes are disposed apart from one another, and the absorption layer is interposed between the liquid-gas separation membranes. The liquid-gas separation membrane is made of a material comprising a hydrophobic substance having pores. INDEPENDENT CLAIMS are included for:    (1) a hydrogen generating apparatus; and    (2) a fuel cell generation system.
