摘要:
The invention relates to a single fuel cell, comprising a) at least two electrochemically active electrodes, separated by a polymer electrolyte membrane and b) at least two separator plates, having at least one respective gas channel for reaction gases, whereby at least one separator plate is composed of glassy carbon. Said invention also relates to methods for producing said single fuel cell as well as to fuel cells, comprising such a single fuel cell.
摘要:
The present invention relates to methods for producing anisotropic shaped bodies, in which a polymer-comprising shaped body is passed through a liquid-filled trough which contains a compound containing at least 2 carbon atoms, wherein the polymers are unwound from one reel and wound onto another reel and the liquid contains monomers containing phosphonic acid groups and/or monomers containing sulphonic acid groups.
摘要:
The present invention relates to a novel proton-conducting polymer membrane based on polyazole block polymers which, owing to their outstanding chemical and thermal properties, can be used widely and are suitable in particular as polymer electrolyte membrane (PEM) for producing membrane electrode units or so-called PEM fuel cells.
