    摘要: A method of estimating a lifespan of a fuel cell including a cathode and an anode which contain catalysts and an electrolyte membrane interposed between the anode and the cathode. A cyclic potential with a voltage ranging from a low voltage to a voltage greater than oxidation voltages of the catalysts is applied between the anode and the cathode and fuel cell performance is measured initially and after a predetermined number of cycles. The lifespan of the fuel cell may estimated based on degradation of cell performance after the predetermined number of cycles, based on CV curves obtained during the cycling of the potential and/or a change in particle size of the catalysts after the predetermined number of cycles.

    摘要: A membrane electrode assembly for a fuel cell, a method of preparing the same, and a fuel cell using the membrane electrode assembly for a fuel cell. The membrane electrode assembly includes an anode comprising an anode substrate, an anode diffusion layer, and an anode catalyst layer having pores; a cathode comprising a cathode substrate, a cathode diffusion layer, and a cathode catalyst layer having pores; and an electrolyte membrane interposed between the cathode and the anode, wherein the anode diffusion layer is hydrophilic and the cathode diffusion layer is hydrophobic, and the average diameter of the pores of the anode catalyst layer is smaller than the average diameter of the pores of the cathode catalyst layer. In the membrane electrode assembly, air can be easily supplied to the cathode and water can easily flow out of the cathode, thereby obtaining high performance of the membrane electrode assembly, and the anode catalyst layer has relatively small pores, thereby improving durability of the anode and reducing the diffusion speed of methanol in the anode catalyst layer to maintain the initial performance of a battery for a long time.
