A new method of increasing the reactivity of ultrathin nanosheets, just a few atoms thick, can someday make fuel cells for hydrogen cars cheaper, finds a new Johns Hopkins study.
WEST LAFAYETTE, Ind. — The 2019 Toyota Mirai electric vehicle touts zero emissions, thanks to a fuel cell that runs on hydrogen instead of gasoline. But the Mirai has barely left California, partly because today’s fuel cell electrodes are made of super expensive platinum.
Cutting down on the platinum would also cut costs, allowing more electric cars to hit the market.
DOE Fact of the Month February 2019: A Process to Produce Hydrogen from Water Using Sunlight Reaches 16.2% Efficiency, on Its Way to Meeting DOE TargetFebruary 19, 2019 | 2 min read February 19, 2019 | 2 min read
Photoelectrochemical (PEC) hydrogen production offers a promising route to affordable and sustainable hydrogen fuel by harvesting light from the sun and using water as feedstock.
Through direct molecular evidence of the chemical transformations at the surface of fuel cell materials, scientists can find ways to optimize cell efficiency.
Jülich– They waited for it to achieve a lifetime of 100,000 hours before gradually bringing their lifetime test to a close a few days ago: researchers from Forschungszentrum Jülich developed a fuel cell and operated it at a temperature of 700 °C for more than 11 years.
Optimized oxides made from common metals use less energy and show the potential of new design approach.
Brussels/Eindhoven– It sounds like magic: you put a dedicated device in contact with air, expose it to sunlight and it starts producing fuel, for free. That is the basic idea behind the fundamental research conducted by DIFFER1, the Dutch Institute for Fundamental Energy Research, in association with Toyota Motor Europe (TME).
In recent years, renewable energy has been on the rise in the United States. Still, the overwhelming majority of our energy comes from fossil fuels. And, renewable energy needs to overcome significant limitations and obstacles to contribute a greater share of our overall energy solution. Hydrogen fuel cells may be the key to our sustainable energy future.
Jülich – Scientists from Jülich together with colleagues from Japan have discovered how fuel cell membranes can be improved without the use of rare and expensive precious metals such as platinum. The anion-exchange membranes studied are a key component of certain polymer electrolyte fuel cells and serve to transfer charged particles (anions) while at the same time retaining gases such as oxygen or hydrogen.
