These devices can efficiently convert chemical energy into electricity or produce hydrogen from water, without carbon emissions. <\/p>\n<p>The cover of the article illustrates a fundamental chemical reaction at the heart of these materials: the interaction of water vapor with the crystalline structure of the electrolyte, which generates mobile protons responsible for proton conduction. Increasing temperature is accompanied by a rise in crystalline symmetry, illustrated by the gradual reduction then disappearance of the octahedral tilt, marking the transition to a purely anionic conducting phase. Protons can persist at high temperatures, up to 800\u00b0C.  <\/p>\n<p>The article provides an in-depth analysis of the structural evolution of these materials as a function of hydration, chemical composition and temperature.<\/p>\n<p>These results provide key insights into the relationship between structure and transport properties, and form a solid basis for the optimization of new proton-conducting electrolytes.<\/p>\n<p>The article is available here for free for 6 weeks: <a href=\"https:\/\/pubs.rsc.org\/en\/content\/articlelanding\/2026\/ta\/d5ta07218b\"><u>https:\/\/pubs.rsc.org\/en\/content\/articlelanding\/2026\/ta\/d5ta07218b<\/u><\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Proton-conducting electrolyte materials for efficient chemical energy conversion and hydrogen  [&#8230;]<\/p>\n","protected":false},"author":1,"featured_media":3770,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[46,51],"tags":[],"class_list":["post-3768","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-events","category-st2e"],"_links":{"self":[{"href":"https:\/\/www.cnrs-imn.fr\/en\/wp-json\/wp\/v2\/posts\/3768","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.cnrs-imn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.cnrs-imn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.cnrs-imn.fr\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.cnrs-imn.fr\/en\/wp-json\/wp\/v2\/comments?post=3768"}],"version-history":[{"count":0,"href":"https:\/\/www.cnrs-imn.fr\/en\/wp-json\/wp\/v2\/posts\/3768\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.cnrs-imn.fr\/en\/wp-json\/wp\/v2\/media\/3770"}],"wp:attachment":[{"href":"https:\/\/www.cnrs-imn.fr\/en\/wp-json\/wp\/v2\/media?parent=3768"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.cnrs-imn.fr\/en\/wp-json\/wp\/v2\/categories?post=3768"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.cnrs-imn.fr\/en\/wp-json\/wp\/v2\/tags?post=3768"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
