Long side chain PFSA

E modulus of long-side-chain PFSA membranes as a function of temperature. Fumapem F950 (EW 900, 50 pm thickness). Nation ... [Pg.48]

CF2=CF0CF2CF2CF2CF2S02F (Figure 2.6). The synthesis of the short-chain PFVESF monomer involves numerous steps, and present yields are not satisfying. However, the short-side-chain PFSA (SSC-PFSA) shows significant improvement in performance compared to the long-side-chain PFSA (LSC-PFSA) and the best balance of properties for fuel cell application in terms of proton conductivity, dimensional stability, mechanical strength, and beginning of life fuel cell performance. ... [Pg.65]

As described earlier, the commercialization of PEMFCs requires lower prices of the membranes and generation systems, compactness of the system, and higher efficiency of power generation. New types of PFSA membranes, new processes of membrane fabrication, and high-temperature membranes have been investigated. This chapter deals with (1) conventional PFSA membranes with long side chains, (2) membranes with short side chains, (3) sulfonimide membranes, and (4) other miscellaneous types of membranes. [Pg.53]
