    摘要： A method of preparing a fuel cell catalyst includes preparing a catalyst precursor solution by mixing a catalyst precursor and a solvent, and subjecting the catalyst precursor solution to radiation of electron beams having energy of less than or equal to 1 MeV. A method of preparing the fuel cell catalyst uses electron beams having low energy so that it can provide a desirable catalyst uniformly in a simple and economical process, as well as releasing few X-rays so that the catalyst can be mass produced.

    摘要： A fuel cell stack including membrane-electrode assemblies and separators formed between each of the membrane-electrode assemblies is disclosed. The membrane-electrode assemblies may each include an electrolyte membrane, an anode formed on a first surface of the electrolyte membrane, and a cathode formed on a second surface of the electrolyte membrane. Each of the separators may include an anode separator facing the anode and a cathode separator facing the cathode. Each of the separators may include at least two manifolds, a channel separated from the manifolds and facing either the anode or the cathode, and a connection channel fluidly connecting the manifold and the channel. The separator may also include a buffer protrusion system in the connection channel configured to disperse the flow of the fuel or the oxidant.

    摘要： An arrangement producing metal nanoparticles includes a γ-ray irradiator installed in a radioactive shielding room, a reactor that is disposed to oppose the γ-ray irradiator, and a power supply installed outside the radioactive shielding room to supply power to the reactor. The reactor includes a container receiving reaction materials and transmitting the energy of γ-rays to reaction materials arranged inside of the reactor, an agitator that is installed in the container to be capable of rotating, and a driving source for receiving the power from the power supply to drive the agitator.
