Abstract Mediated fuel cells (MedFCs) offer a promising alternative to proton exchange membrane by addressing key challenges such as reliance on precious metal catalysts and complex water thermal management through the use of redox mediators efficient oxygen reduction reaction (ORR) facilitators. However, currently available exhibit either low electrochemical activity or insufficient stability, which constrains performance durability these cells. In this study, Dawson‐type 18‐molybdophosphoric heteropoly acid (18‐PMA) with high stability is introduced an ORR mediator in mediated cells, utilizing ordinary carbon felt electrodes. The cell employing 18‐PMA achieved maximum steady‐state power density 600 mW cm⁻ 2 under dry gas conditions demonstrated stable discharge at current densities ranging from 100 500 mA , long‐term ensured simple convenient replacement Fe‐N‐C catalyst external reactor.

Photochromic films have attracted increasing attention for their potential in information storage and photoswitchable devices. Developing novel photochromic materials is still a highly challenging topic. In this work, we successfully obtained an unprecedented mixed-heteroatom-templated ErIII-incorporated polyoxometalate [H2N(CH3)2]18Na2K2H12{Er2(H2O)10W14O43[SeTeW15O54][B-α-TeW9O33]2}2·117H2O (1) by concurrently introducing the [TeO3]2– [SeO3]2– heteroanion templates into Er3+/WO42– system. The most attractive feature that polyoxoanion of 1 consists three kinds building units such as classical trivacant Keggin [B-α-TeW9O33]8–, rarely seen TeIV–SeIV-oriented Dawson-like [SeTeW15O54]10–, extraordinary [W14O43]2– with infrequent [WVIO7(WVI5O20)]18– pentagon subunit. Based on photochromism polyoxometalates presence organic electron donors under light irradiation, composite film GEL/TEG/1 was fabricated mixing gelatin (GEL) triethylene glycol (TEG). shows good properties 365 nm UV irradiation. changed color within 15 min endow fast easy "'printing'" performance.
