Abstract
Official abstract text for this publication.
An electrolyte membrane having a structure wherein fine rubber particles having substantially no ion-conducting group and having an average particle size of 20 nm to 1 μm are uniformly dispersed in a matrix including a resin component having ion-conducting group. The electrolyte membrane has high bonding ability to electrodes and does not cause cracks and ruptures because it is kept flexible even under low humid or absolutely dried condition, in addition, shows high ion conductivity even under low humid or absolutely dried condition because the matrix having ion-conducting groups are continuous.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrolyte membrane, comprising: a structure comprising an aggregate of at least one fine core-shell particle, wherein a core of the core-shell particle comprises, as a core, at least one fine rubber particle with an average particle size of 20 nm to 1 μm and with a content of less than 5 mol % of monomer units comprising ion-conducting groups, wherein the fine rubber particle is uniformly dispersed in a matrix comprising a resin component, wherein…
