TL;DR: In this article, a solution-cast method for self-humidifying membranes of proton exchange membrane fuel cells (PEMFCs) was developed, which can increase the strength of the fuel cells and reduce the membrane conductivity loss under dry conditions.

TL;DR: In this study, phytic acid was first immobilized by MIL101 via vacuum-assisted impregnation method and utilized as a novel filler to incorporate into Nafion to fabricate hybrid proton exchange membrane for application in PEMFC under different relative humidities (RHs), especially under low RHs.
Abstract: In this study, phytic acid (myo-inositol hexaphosphonic acid) was first immobilized by MIL101 via vacuum-assisted impregnation method. The obtained phytic@MIL101 was then utilized as a novel filler to incorporate into Nafion to fabricate hybrid proton exchange membrane for application in PEMFC under different relative humidities (RHs), especially under low RHs. High loading and uniform dispersion of phytic acid in MIL 101(Cr) were achieved as demonstrated by ICP, FT-IR, XPS, and EDS-mapping. The phytic@MIL101 was dispersed homogeneously in the Nafion matrix when the filler content was less than 12%. Hybrid membranes were evaluated by proton conductivity, mechanical property, thermal stability, and so forth. Remarkably, the Nafion/phytic@MIL hybrid membranes showed high proton conductivity at different RHs, especially under low RHs, which was up to 0.0608 S cm–1 and 7.63 × 10–4 S cm–1 at 57.4% RH and 10.5% RH (2.8 and 11.0 times higher than that of pristine membrane), respectively. Moreover, the mechanical...

TL;DR: In this paper, layered silicates are incorporated into polymer membranes to reduce swelling significantly in hot water; they also help to decrease methanol permeability, and the polymer/clay composite membranes show thermal stability to 240°C and (3.5)×10−3 S cm−1 proton conductivity at room temperature.
