摘要： The invention relates to a process for recycling fuel cell components containing fluorine-containing and precious metal-containing constituents: in this process, the fluorine-containing constituents are separated off from the precious metal-containing constituents by treatment with a medium present in the supercritical state. Preference is given to using water as supercritical medium. After the fluorine-containing constituents have been separated off, the precious metal-containing residues can be recovered in a recycling process without harmful fluorine or hydrogen fluoride emissions. The fluorine-containing constituents can likewise be recovered. The process is used in the recovery of precious metals and/or fluorine-containing constituents from membrane fuel cells, electrolysis cells, batteries, sensors and other electrochemical devices.

摘要： The invention describes a process for producing a gas diffusion electrode which has a catalyst layer having a smooth surface, wherein the smooth surface of the catalyst layer is produced by bringing the catalyst layer in the moist state into contact with a transfer film and removing this transfer film after drying. In variant A, the catalyst layer is firstly produced on a transfer film and then transferred in the moist state to the gas diffusion layer. In variant B, the catalyst layer is applied to the gas diffusion layer, and a transfer film is then placed on top. In both cases, the structure produced in this way is subsequently dried. Before further processing, the transfer film is removed to give a gas diffusion electrode having a smooth catalyst surface which has a maximum profile peak height (Rp) of less than 25 microns. The electrodes are used for producing membrane-electrode assemblies for membrane fuel cells or other electrochemical devices. Membrane-electrode assemblies comprising the gas diffusion electrodes of the invention display very good long-term behaviour.
摘要翻译：本发明描述了一种制备具有光滑表面的催化剂层的气体扩散电极的方法，其中催化剂层的平滑表面是通过使处于潮湿状态的催化剂层与转移膜接触并除去该转移而产生的干燥后胶片。在变型A中，催化剂层首先在转移膜上产生，然后在潮湿状态下转移到气体扩散层。在变型B中，将催化剂层施加到气体扩散层，然后将转印膜放置在顶部。在这两种情况下，以这种方式生产的结构随后被干燥。在进一步处理之前，去除转移膜，得到具有平滑催化剂表面的气体扩散电极，其具有小于25微米的最大轮廓峰高（Rp）。电极用于生产膜燃料电池或其他电化学装置的膜 - 电极组件。包括本发明的气体扩散电极的膜 - 电极组件显示出非常好的长期行为。

摘要： The invention relates to Membrane Electrode Assemblies (“MEAs”) for solid-polymer-electrolyte proton-conducting membrane fuel cells (“PEM-FCs”) having better performance and improved durability, in particular when operated under severe electrochemical conditions such as fuel starvation and start-up/shut-down cycling. The MEAs are characterized in that at least one of its two electrode layers (EL1 and/or EL2) contains a first electrocatalyst (EC1) comprising an iridium oxide component in combination with at least one other inorganic oxide component and a second electrocatalyst (EC2/EC2′), which is free from iridium. Preferably, an iridium oxide/titania catalyst is employed as EC1. The MEAs reveal better performance, in particular when operated under severe operating conditions such as fuel starvation and start-up/shut-down cycling.
