A nickel–hydrogen battery (NiH 2 or Ni–H 2) is a rechargeable electrochemical power source based on nickel and hydrogen. [5] It differs from a nickel–metal hydride (NiMH) battery by the use of hydrogen in gaseous form, stored in a pressurized cell at up to 1200 psi (82.7 bar ) pressure. [ 6 ]
The catalytic performance of Mo3P nanoparticles is tested in the hydrogen evolution reaction (HER), indicating an onset potential of as low as 21 mV, H2 formation rate, and exchange current density of 214.7 μmol/(s·g) cat (at only 100 mV overpotential) and 279.07 μA/cm 2, respectively, which are among the closest values yet observed to platinum.
Hydrogen battery may refer to: Nickel–hydrogen battery , a rechargeable battery with a power source based on nickel and hydrogen Hydrogen fuel cell , an electrochemical cell that uses hydrogen as a fuel source

Hydrogen gas is produced by several industrial methods. [1] Nearly all of the world's current supply of hydrogen is created from fossil fuels. [2] [3]: 1 Most hydrogen is gray hydrogen made through steam methane reforming.
The nickel–hydrogen battery was used for the first time in 1977 aboard the U.S. Navy's Navigation technology satellite-2 (NTS-2). [85] The International Space Station , [ 86 ] Mars Odyssey [ 87 ] and the Mars Global Surveyor [ 88 ] are equipped with nickel-hydrogen batteries.
