ABSTRACT:
A gas diffusion electrode is now prepared which offers extended, efficient operation. For this, the electrode matrix may include a hydrophobic layer containing hydrophobic polymer. The electrode has hydrophilic ingredient of particulate carbon bound by hydrophilic, halogenated polymer binder. The particulate carbon used is a catalyzed carbon. The resulting efficient electrode is capable of extended operation. Moreover, on the one hand carbon catalysis can now be done in economical, straightforward manner, while on the other hand the electrode can have a surface overlay of a dimensionally stable, thin non-cellulosic paper. Such paper may be pressed against the underlying component material by a foraminous overlay, e.g., a metal mesh.
