Polylactic acid-based composition and film formed thereof

The present invention relates to a polymer electrolyte that provides high proton conductivity and low fuel crossover at the same time, as well as a member using the same. The embodiments of the invention can achieve high output and high energy density in the form of a polymer electrolyte fuel cell. A polymer electrolyte comprising a proton conductive polymer (A) and a polymer (B) which is different from (A) wherein a ratio of the amount of unfreezable water, represented by formula (S1), in said polymer electrolyte is no less than 40 wt % and no greater than 100 wt % is disclosed. The ratio of amount of unfreezable water (S1)=(amount of unfreezable water)/(amount of low melting point water+amount of unfreezable water)&#xd7;100 (%).

Polymer electrolyte as well as polymer electrolyte membrane, membrane electrode assembly and polymer electrolyte fuel cell using the same

A polymer electrolytic material has excellent proton conductivity and excellent fuel shutting property, and accordingly provide a polymer electrolytic fuel cell with a high efficiency. This polymer electrolytic material has an unfreezable water ratio Rwdefined by the following expression (S1) in a range of 20 to 100% by weight in hydrated state:1=[/()]&#xd7;100&#x2003;&#x2003;(S1)in which Wnf represents the unfreezable water content per 1 g of the polymer electrolytic material in dry state and Wfc represents the low freezing point water content per 1 g of the polymer electrolytic material in dry state.

Membrane electrode complex and solid type fuel cell using it

When forming a separating functional layer containing crosslinked polyamide, by carrying this out in the presence of 1) carboxylic acid ester with a total of 8 or more carbons, or 2) carboxylic acid, it is possible to provide a composite semipermeable membrane which, while still maintaining a high rejection rate, is more outstanding in its water permeability than hitherto.
