摘要： A gas diffusion electrode includes: an electrode catalyst layer (13); porous layers (11, 12) arranged on the electrode catalyst layer (13) and including at least two layers: a second porous layer (12) and a first porous layer (11) formed from materials having different water repellencies, wherein the second porous layer (12) arranged at the side of the electrode catalyst layer (13) has a higher water repellency than the first porous layer (11); and oxidizer gas diffusion substrate (10) arranged on the porous layers (11, 12) and formed by carbon fiber. According to the gas diffusion electrode, it is possible to improve the water repellency of the generated water from the electrode catalyst layer to the gas diffusion layer, the moisture retention and the gas diffusion characteristic of the electrode catalyst layer. Moreover, a solid- state high-molecular electrolyte type fuel cell enables stable electricity generation characteristic even under an operation condition of a wide humidity range and a wide current density region.

摘要： A gas diffusion layer (10) for a fuel cell includes a conductive microparticle layer (2) and a base material layer (1). The conductive microparticle layer (2) is formed with first pores (3) of no less than 0.5 µm and no more than 50 µm and second pores (4) of no less than 0.05µm and less than 0.5µm. Pores (11) are also formed in the base material layer (1). A total volume of the second pores (4) is no less than 50% and less than 100% of a total volume of all of the pores in the conductive microparticle layer (2). By properly setting a pore size D1 of pores having a maximum volume ratio from among the first pores 3, water passages are formed in the first pores (3) separately from gas passages formed in the second pores (4).

摘要： The invention is to provide a gas diffusion layer for fuel cells having excellent adaptability against load change by attaining a good balance between anti-dry-out properties and anti-flooding properties . The gas diffusion layer for fuel cells containing a substrate layer and an conductive fine particle layer is formed by coating a coating liquid for forming the conductive fine particle layer on at least one surface of a substrate for forming the substrate layer using a gravure roll and by a kiss coating. In coating of the coating liquid, a speed difference is generated between a line speed of transferring the substrate and a circumferential speed of the gravure roll, and apparent viscosity [.eta. (Pa .cndot.s) ] of the coating liquid as determined by type B viscosimeter satisfies the following relations: 1.0

摘要： Disclosed is a gas diffusion layer (10) for use in a fuel cell, which comprises an electrically conductive microparticle layer (2) and a base layer (1). The electrically conductive microparticle layer (2) has, formed therein, first void spaces (3) each having a diameter of 0.5 to 50 µm inclusive and second void spaces (4) each having a diameter of not smaller than 0.05 µm and smaller than 0.5 µm. The base layer (1) also has void spaces (11) formed therein. The total volume of the second void spaces (4) is not less than 50% and less than 100% relative to the total volume of the void spaces contained in the electrically conductive microparticle layer (2). With respect to void spaces having a specific diameter (D1) and occupy the largest volume fraction among the first void spaces (3), the diameter (D1) is set so that a capillary force (F1) that acts on the first void spaces (3) is smaller than a capillary force (F2) that acts on the void spaces (11) contained in the base layer (1). In this manner, the first void spaces (3) are directed to work as water passages and the second void spaces (4) are directed to work as gas passages.
