The invention discloses a passive emergency power generation system and a nuclear power station comprising the passive emergency power generation system.The passive emergency power generation system comprises a passive heat exchange device, an air inlet duct, an air exhaust duct and a power generation device, and the passive heat exchange device is located in a reactor pit in a containment vessel; the passive heat exchange device comprises an air inlet duct and an air exhaust duct which are arranged around a reactor container in a reactor pit, the air inlet duct and the air exhaust duct both penetrate through a containment and then are communicated with the passive heat exchange device, an air inlet of the air inlet duct and an air outlet of the air exhaust duct are both located outside the containment, a height difference exists between the air inlet duct and the air exhaust duct, and the power generation device comprises an impeller. The impeller is arranged in the exhaust duct, and after air passing throug
