Influence of Ink Composition and Drying Technique on the Performance and Stability of Fe‐N‐C‐based High‐Temperature Proton Exchange Membrane Fuel Cells

open access: yesChemSusChem, Accepted Article.
Fe‐N‐C catalysts have emerged as a potentially cost‐effective alternative to Pt‐based catalysts in high‐temperature polymer electrolyte membrane fuel cell cathodes. However, the optimal design and deposition method of Pt‐free catalyst layer remains unclear.

In situ loading of a pore network model for quantitative characterization and visualization of gas seepage in coal rocks

open access: yesDeep Underground Science and Engineering, EarlyView.
Fine modeling of a three‐dimensional fracture structure under dynamic loading of coal is carried out. The streamline distribution law of pressure and velocity field in the loading process of the coal specimen is analyzed, the absolute permeability of the coal specimen is calculated, and the feasibility of the pore network model algorithm and finite ...

Review of artificial intelligence applications in geothermal energy extraction from hot dry rock

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper systematically summarized the applications of artificial intelligence (AI) in hot dry rock (HDR) geothermal exploitation and discussed the limitations and opportunities. A novel intelligent HDR exploitation system was proposed to promote the development of HDR toward more efficiency, economy, and intelligence.
