- Description
- Energy is one of the most important factors that
will influence the shape of society in the 21st century. Fuel cells
are electrochemical energy converters, transforming chemical energy
directly into electricity. Fuel cells are the main zero emission
energy converters fed with hydrogen or renewable fuels like
methanol and ethanol to power vehicles, portable devices or to
supply electricity to buildings. Fuel cell technology will forever
change our concept of alternative energy systems and will become
the driver of the next growth wave of the world’s economy. A proton
conductive membrane is the core of the polymer electrolyte membrane
fuel cell (PEMFC). Presently, Nafion® membranes are widely used in
PEMFC. However, the high cost, low operation temperature
(<80°C), propensity for dehydration, high methanol crossover,
and environmental recycling uncertainties of Nafion® and other
similar fluorinated membranes are limiting their widespread
commercial application in PEMFC and DMFC [1-3]. Therefore,
developing cheaper membranes with low methanol crossover have
become an active area of research We developed low-cost proton
conductive membranes based on non-fluorinated polymer. The
membranes are thermally and chemically stable, mechanically strong,
highly proton conductive and have low fuel
crossover.
