To exist as a liquid, H2 must be cooled below hydrogen's critical point of 33 K (-400.27ºF / -240.15ºC).
For hydrogen to be in a full liquid state without evaporating at atmospheric pressure, H2 needs to be cooled to 20.28 K (−423.17 °F /−252.87°C).

Is hydrogen a liquid or gas?
Hydrogen is a gas at room temperature.
Which substance has the smallest temperature range as a liquid hydrogen or nitrogen?
HydrogenWater
Is hydrogen bromide a solid liquid or a gas at room temperature?
Hydrogen bromide (HBr) is a gas at room temperature.
Hydrogens phase of matter at room temperature?
Gas. Unquestionably. Consider the alternative: Liquid? Solid? Maybe plasma? Liquid and solid hydrogen only produced in near the absolute temperature. Plasma on the other hand requires enormous temperature and pressure (Sun).
Why hydrogen chloride is a liquid while hydrogen chloride is a gas?
At the standard temperature and pressure, hydrogen chloride exists as a gas. It does not exist in liquid state, but in aqueous medium along with water as a solvent.
