The invention discloses a distributed passive hydrogen safety protection system, comprising an active hydrogen concentration monitoring system and a passive hydrogen concentration control system. The passive hydrogen concentration control system comprises a housing, and an air entraining zone, a catalytic zone and an air guide zone which are successively distributed in the housing from down to top, wherein the air entraining zone employs an inner trapezoid design, and is used for entraining external hydrogen and air; the catalytic zone employs a Pt or Pd material as a catalyst, and is used for mixing hydrogen, air and catalysts to realize passive catalytic reaction; the air guide zone is used for discharging residual air after catalysis and generated steam. The active hydrogen concentration monitoring system is used for monitoring the concentration of hydrogen introduced into the air entraining zone, and controlling the amount of hydrogen entering the air entraining zone. In accidents of hydrogen leakage, hydrogen blast, etc., the distributed passive hydrogen safety protection system can automatically and passively perform hydrogen safety protection without artificial additional active control, not only greatly improve hydrogen place safety, but also meet different place demands on hydrogen safety protection.
