However, PTFE also limits the formation of an effective triple-phase boundary (TPB) due to its strong resistance to acid retention. To obtain the composite ionomer in the CL of HT-PEMFC, polybenzimidazole (PBI) is thus invited. Then, an in situ quaternization strategy on PBI is developed to increase the TPB concentration in CL by controlling the PA distribution and taking into account the superior PA retention capability of quaternary ammonium groups. At the same time, Pt active sites can be freed and mass transfer channels can be in situ constructed. Consequently, the corresponding HT-PEMFC fed with H₂/O₂ attains a maximum power density of 755 mW/cm² and an electrochemical surface area of 35.56 cm²/mg_Pt, surpassing those equipped with PTFE by 10 and 30%, respectively.

Here, a phase-change material-integrated dual-mode Janus film with enhanced radiative cooling and SH for thermal management is demonstrated. The Janus film is developed by integrating a paraffin-type phase-change material (PCM) and carbon nanotube (CNT)-modified poly(dimethylsiloxane) (PDMS), enabling both PRC and SH. The cooling mode of Janus film is achieved by infrared ray thermal radiation of PDMS and absorbing heat of PCM. The heating mode of Janus film is achieved by SH of the CNTs@PDMS layer, and solar energy is converted into heat energy stored and released by PCM@PDMS. The introduction of PCM enhances the practical effects of radiation cooling and SH. The energy storage of PCM can be released at night, avoiding unwanted overcooling. In addition, the PCM@PDMS features self-cleaning and self-repair abilities.
