Abstract
Using UV-curing technique the proton conductive polymer materials based on acrylic monomers: 2-acrylamido-2-methylpropane sulfonic acid (AMPS), acrylic acid (AA) and acrylonitrile (AN), cross-linked by varying amounts of N,N'-methylene(bis)acrylamide (MBA), and the hybrid polymer/inorganic membrane of the same content with addition of sol-gel system (SGS) based on 3-methacryloxypropyl trimethoxysilane (MAPTMS) and tetraethoxysilane (TEOS) were synthesized. The obtained materials were characterized by analysis of thermal, mechanical and morphological properties. Proton conductivity and water uptake were found to depend on the level of cross-linking of the materials. The value of proton conductivity of the hybrid membrane was sufficiently high reaching 3.46 × 10-2 S cm-1.

Summary
Nowadays one can observe the trend for searching new methods for energy generation because of the reduced availability of the traditional non-renewable energy resources. Alternatives seem to be fuel cells – electrochemical energy devices, using the energy from chemical reactions between a fuel and an oxidant [1,2,3]. The main components of a fuel cell are anode, cathode and electrolyte. Among different types of fuel cell the polymer exchange membrane fuel cells (PEMFC) have many advantages: relatively low operating temperature, long service life, low cost and possibility for fast startups. The core component of PEMFC is a polymer electrolyte membrane (PEM) sandwiched between the electrodes. High-performance membrane material is a challenge for researchers as the effective PEMFC operation is related to PEM effectiveness. The PEMs have to meet the requirements of high proton conductivity, electrical isolation, impermeability to fuel and oxidant alongside with thermal and chemical stabilities
