Kationische Polyelektrolyte werden in alkalischen Brennstoffzellen als Anionenaustauschmembranen (AEMs) verwendet, um Kraftstoff in Elektrizität umzuwandeln. C. Tang et al. berichten in ihrer Zuschrift auf S. 2412 über eine Klasse von Metallopolyelektrolyten, die für chemisch inerte AEMs unter stark basischen Bedingungen konzipiert wurden. Die AEMs zeigen exzellente thermische, chemische und mechanische...
Chemically inert, mechanically tough, cationic metallo‐polyelectrolytes were conceptualized and designed as durable anion‐exchange membranes (AEMs). Ring‐opening metathesis polymerization (ROMP) of cobaltocenium‐containing cyclooctene with triazole as the only linker group, followed by backbone hydrogenation, led to a new class of AEMs with a polyethylene‐like framework and alkaline‐stable cobaltocenium...
