It is provided a pentafluorophosphate derivative according to general formula (I): or a pharmaceutically acceptable salt or solvate thereof. Thereby, Rand Rdenote independently from each other H or F; Rdenotes H, a C-Calkyl optionally substituted by a hydrocarbon chain comprising an amide function and/or a carboxyl function, or by a substituent chosen from the group consisting of alkyl, alkylamino, alkylaminocarboxy, carboxy, alkoxycarbonyl, hydroxy, N-morpholino, N-morpholinoalkyl, N-morpholinocarbonyl, N-methyl-N-piperazinyl, N-methyl-N-piperazinylalkyl, N-methyl-N-piperazinylcarbonyl, and sulfo, an optionally substituted C-Ccycloalkyl, or an optionally substituted C-Caryl, wherein a hydrocarbon chain of the alkyl, the cycloalkyl or the aryl can be interrupted by one or more oxygen, sulfur and/or nitrogen atoms; and M denotes any cation; with the proviso that at least one of Rand Rdenotes F, if Rdenotes H.

Pentafluorophosphate derivative, its uses and an appropriate manufacturing method

The invention relates to a proton-conducting polymer membrane and to a method for the production thereof. Starting from a catalyst layer, which is homogeneously deposited on the polymer membrane (), the catalyst layer is subdivided into a number of catalyst segments () by microstructuring so that adjacent fuel cell units of a planar fuel cell arrangement can be realized in the smallest possible space.
