New Fuel Cell Design Makes Double the Voltage
March 19, 2019 | 2 Comments
Washington University in St. Louis engineers have developed a high-powered fuel cell that operates at double the voltage of today’s commercial fuel cells. It could power underwater vehicles, drones and eventually electric aircraft at a significantly lower cost. The transportation industry is one of the largest consumers of energy in the U.S. economy with increasing […]

Fuel Cell With 10 Times the Power With 10% of the Platinum
March 14, 2019 | 2 Comments
Purdue University researchers produce a fuel cell with a new method increasing the fuel cell electrode activity at least tenfold and using 90 percent less platinum. Electric vehicles running on fuel cells tout zero emissions and higher efficiency, but expensive platinum is holding them back from entering a larger market. The 2019 Toyota Mirai electric […]

Making The Case For Lithium and Sulfur Air Batteries
March 12, 2019 | 1 Comment
Brazil’s Fundação de Amparo à Pesquisa do Estado de São Paulo is adding strength to case for lithium air batteries. Current lithium ion battery technology will probably not be able to handle the coming decades’ huge demand for energy. It is estimated that by 2050, electricity will make up 50% of the world’s energy mix. […]

Cooling With A LED
March 7, 2019 | Leave a Comment
A University of Michigan finding runs counter to a common assumption in physics. The researchers ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away. The approach could lead to new solid-state cooling technology for future microprocessors, which will have so many transistors packed into a small […]
