Materials scientists at Harvard University have developed a new type of solid oxide fuel cell (SOFC) by using low-temperature operation and using nano-structured vanadium oxide as the anode material, which can generate electricity and store electrochemical energy even when hydrogen fuel is depleted. Keep running for a while. The researchers believe that, theoretically, this hydrogen fuel cell can be used for small-sized portable devices such as drones, because additional storage energy can significantly extend the use of the device.
Thin-film solid oxide fuel cells traditionally use platinum as the electrode, which can only generate electricity for about 15 seconds before the electrochemical reaction stops. The new solid oxide fuel cell uses platinum and vanadium oxide bilayer anodes and can continue to operate for more than 14 times (3 minutes 30 seconds, current density 0.2 mA/cm2) without fuel. Researchers will conduct application testing within two years. (Golden Wave)
