Hydrogen gas (dihydrogen or molecular hydrogen) is highly flammable: 2 H2(g) + O2(g) → 2 H2O(l) (572 kJ/2 mol = 286 kJ/mol = 141.865 MJ/kg) The enthalpy of combustion is −286 kJ/mol. Hydrogen gas forms explosive mixtures with air in concentrations from 4–74% and with chlorine at 5–95%. The explosive reactions may be triggered by spar… WebA small decrease (V H2 = 110 mL min −1) barely limits the polarization curve but is already visible in the current density distribution in Figure 4c. At V H2 = 65 mL min −1 …

WebMolar Mass / Molecular Weight of H2: Hydrogen Gas Wayne Breslyn 633K subscribers 98K views 4 years ago Explanation of how to find the molar mass of H2: Hydrogen Gas. A few things to consider... WebHydrogen has a low energy density. While the energy per mass of hydrogen is substantially greater than most other fuels, as can be seen in Figure 1, its energy by volume is much less than liquid fuels like gasoline. For a 300 mile driving range, an FCEV will need about 5 kg of hydrogen. At 700 bar (~10,000 psi) a storage system would have a merchant surcharge
