A fuel cell including a absorbing member is provided to improve performance and reliability of the fuel cell. The fuel cell includes an electricity generation unit and a medium member. The electricity generation unit includes a fuel supply unit, and a membrane electrode assembly (MEA), absorbing member, and air supply unit. A fuel is supplied through the medium member, and air is supplied through the air supply unit. During oxidation/reduction reaction between a fuel and air, condensed moisture or water is produced inside fuel cell, and the condensed moisture can block path of air flow into the fuel cell. In order to solve this problem, absorbing member is disposed between the membrane electrode assembly and the air supply unit. The absorbing member effectively absorbs moisture and blocking of air flow path by the moisture is prevented.

The present invention relates to a membrane-electrode assembly for a fuel cell and a fuel cell system comprising the same. The membrane-electrode assembly includes an anode and a cathode facing each other and a polymer electrolyte membrane positioned therebetween. The polymer electrolyte membrane adheres to the anode through a binder disposed between the polymer electrolyte membrane and the anode, and adheres to the cathode through a binder disposed between the polymer electrolyte membrane and the cathode. The binder and the polymer electrolyte membrane can include a cation exchange resin and an inorganic additive.

A micro reforming reactor includes a first substrate with a micro channel having a width of less than 1,000 μm bonded to a second substrate to form a micro tunnel. An adhesive layer is formed on the internal walls of the micro tunnel using a flow coating method. A catalyst may then be optionally formed on the adhesive coated internal walls of the micro tunnel, also using a flow coating method.

The membrane-electrode assembly for a fuel cell includes an anode and a cathode facing each other and a polymer electrolyte membrane interposed therebetween. The cathode includes an electrode substrate and a catalyst layer disposed on the electrode substrate, and the catalyst layer has a mesopore volume ranging from 0.013 to 0.04 cm3/g. The membrane-electrode assembly has low mass resistance and contributes to the overall increased performance of the fuel cell by having optimal pore volumes (e.g., mesopore volume) in a cathode catalyst layer to provide ease of transfer and release of materials within the membrane-electrode assembly of the fuel cell.
