Paschen's law is an equation that gives the breakdown voltage, that is, the voltage necessary to start a discharge or electric arc, between two electrodes in a gas as a function of pressure and gap length. [2] [3] It is named after Friedrich Paschen who discovered it empirically in 1889. [4]
Louis Carl Heinrich Friedrich Paschen (22 January 1865 – 25 February 1947) was a German physicist, known for his work on electrical discharges. He is also known for the Paschen series , a series of hydrogen spectral lines in the infrared region that he first observed in 1908.
For example, the 2 → 1 line is called "Lyman-alpha" (Ly-α), while the 7 → 3 line is called "Paschen-delta" (Pa-δ). Energy level diagram of electrons in hydrogen atom. There are emission lines from hydrogen that fall outside of these series, such as the 21 cm line.
BMW's new fuel cell car might one day use hydrogen fuel from Plug Power...if Plug Power is still around to sell that fuel.
A hydrogen tank (other names- cartridge or canister) is used for hydrogen storage. [89] [90] [91] The first type IV hydrogen tanks for compressed hydrogen at 700 bars (70 MPa; 10,000 psi) were demonstrated in 2001, the first fuel cell vehicles on the road with type IV tanks are the Toyota FCHV, Mercedes-Benz F-Cell and the GM HydroGen4.
A truck powered by hydrogen traveled 1,806 miles on a single tank of hydrogen with zero emissions and set a new Guinness World Record. ... carrying 386 pounds of hydrogen fuel. Throughout the ...
