Title (EN) CHEMICALLY LINKED HYDROGEL MATERIALS AND USES THEREOF IN ELECTRODES AND/OR ELECTROLYTES IN ELECTROCHEMICAL ENERGY DEVICES
(FR) MATÉRIAUX HYDROGELS LIÉS CHIMIQUEMENT ET LEURS UTILISATIONS DANS DES ÉLECTRODES ET/OU DES ÉLECTROLYTES DANS DES DISPOSITIFS À ÉNERGIE ÉLECTROCHIMIQUE
Abstract: front page image
(EN)A chemically linked catalyst-binder hydrogel material comprised of a water-insoluble chemical hydrogel is useful in, for example, fuel cells, batteries, electrochemical supercapacitors, semi-fuel cells etc. The water-insoluble chemical hydrogel is prepared by a chemical cross-linking reaction between a polymer (such as PVA or chitosan or gelatin) and an aqueous cross-linking agent such as glutaraldehyde, which is catalyzed by protic acid under ambient conditions of temperature and pressure.
(FR)Un matériau hydrogel de catalyseur et de liant lié chimiquement et composé d'un hydrogel chimique insoluble dans l'eau est utile dans, par exemple, des piles à combustible, des batteries, des surcondensateurs électrochimiques, des demi-piles à combustible, etc. L'hydrogel chimique insoluble dans l'eau est préparé au moyen d'une réaction de réticulation chimique entre un polymère (tel que le PVA, le chitosane ou la gélatine) et un agent de réticulation aqueux, tel le glutaraldéhyde, qui est catalysé par un acide protique dans des conditions ambiantes de température et de pression.
