Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Electrocatalytic upgrading of CO to value-added multi-carbon (C2+) compounds is a promising approach to efficient carbon utilization. However, current full-cell systems have low energy conversion effi-ciencies under practical conditions due to the requirem ...

The present invention relates to a method for preparing a catalyst comprising the steps of a. dissolving two or more alloy metal salts, b. adding at least one chelating agent and at least one stabilising agent, forming a sol, c. adding an encapsulant to ...

Anion exchange membrane water electrolyzer (AEMWE) is a potentially cost-effective technology for green hydrogen production. Although the normal current densities of AEMWEs are below 3 A ⋅ cm−2, operating them at higher current densities represents an effi ...

Zero-gap membrane electrode assembly (MEA) CO electrolyzer stands as a promising technology for circular carbon economy. However, current CO electrolyzers are energetically inefficient when operating at ampere-level current densities. Here, by analyzing th ...

Hydroxide exchange membrane fuel cell (HEMFC) is a potentially cost-effective energy conversion technology. However, current state-of-the-art HEMFCs require a high loading of platinum-group-metal (PGM) catalysts, especially for the hydrogen oxidation react ...

Electrochemical CO reduction can potentially serve as an intermediate step for the efficient conversion of CO2 to chemical fuels using renewable electricity. Although membrane electrode assembly (MEA) CO electrolyzers are industrially relevant, they curren ...
