EDX8800M Max XRF spectrometer is applied to the analysis of platinum metal film electrode catalytic layer of nickel and iron
Membrane electrode (be electrode assembly, MEA) is the core component of proton exchange membrane fuel cell, by inside and outside respectively by the proton exchange membrane (proton exchange be, PEM), catalytic layer (catalystlayer, (CL) and the gas diffusion layer gas coursing together layer, GDL) of three parts. Catalytic layer is mainly composed of Pt/C catalyst and perfluorinated sulfonic acid ion polymer (ionomer) through a certain method blend to transfer to the PEM or GDL preparation. Pt nanoparticles, ionomer contact with gas three-phase interface, is the activity of catalyst sites. Among them, the surface of Pt nanoparticles have catalytic H2, O2, and have the effect of transmission electron with the carbon carrier, whereas ionomer passing hydrogen ions H +. Catalysts and porosity of gas diffusion between ionomer and product water provides a channel. Is the most commonly used PEMFC catalyst materials Pt catalyst, because under the condition of low temperature, acidity, the catalytic activity of Pt is the supreme, other catalytic activity obviously weaker than Pt catalyst materials, metal elements doping of iron, nickel, a defect in a crystal structure may be increased, making lithium ion in the interlayer embedded easier, improve lithium ion migration velocity, the structure of the stable material , making the materials exhibit more excellent electrochemical performance.
