The claimed composite catalyst materials comprise iridium oxide (IrO2) and optionally ruthenium oxide (RuO2) in combination with a high surface area inorganic oxide (for example TiO2, Al2O3, ZrO2 and mixtures thereof). The inorganic oxide has a BET surface area in the range of 50 to 400 m2/g, a water solubility of lower than 0.15 g/l and is present in a quantity of less than 20 wt. % based on the total weight of the catalyst. The claimed catalyst materials are characterised by a low oxygen overvoltage and long lifetime in water electrolysis. The catalysts are used in electrodes, catalyst-coated membranes and membrane-electrode-assemblies for PEM electrolyzers as well as in regenerative fuel cells (RFC), sensors, and other electrochemical devices.

摘要： A method of and apparatus for controlling electric discharge machining in which a machining gap formed between a tool electrode and a workpiece is maintained at an essentially constant size based on a reference servo-feed voltage, and in which a jump action, for moving a tool electrode up and away from a workpiece, and returning it to a position close to the workpiece is controlled. The reference servo-feed voltage and conditions for jump action are optimally set to required values during machining according to the discharge stability. The discharge stability is obtained by comparing the actual values of characteristics required for specifying gap condition, e.g., waiting time for a discharge to occur, the voltage during the waiting time, discharge frequency, to the corresponding theoretical values. The theoretical values are calculated in part according to given machining conditions. Therefore, even when machining conditions change as machining progresses, jump action and servo-feed action are properly controlled.
摘要翻译：一种用于控制放电加工的方法和装置，其中形成在工具电极和工件之间的加工间隙基于参考伺服进给电压保持在基本上恒定的尺寸，并且其中用于移动工具的跳动电极向上并远离工件，并将其返回到靠近工件的位置。根据放电稳定性，参考伺服进给电压和跳转动作条件在加工期间最佳设定为所需值。通过将用于指定间隙条件所需的特性的实际值（例如，放电发生的等待时间，等待时间内的电压，放电频率）与相应的理论值进行比较来获得放电稳定性。理论值根据给定的加工条件部分计算。因此，即使在加工过程中加工条件发生变化，也可以适当地控制跳动动作和伺服进给动作。

摘要： An electrochemical fine processing apparatus for electrochemically performing an adding processing and a removing processing of a substance such as a metal or a polymer in a solution in order to produce a structure having a high aspect ratio. Removing electrodes for applying an electric potential opposite to that applied to an addition electrode are disposed around the addition electrode, whereby an excess portion of metal or polymer film pattern can be scraped electrochemically. In addition, alternate electric potential pulses are applied successively to the addition electrode and then to the removing electrodes. It becomes possible to form on the support a structure with sharp pattern edge portions and a high aspect ratio.
