An inflator (14) for inflating an inflatable vehicle occupant protection device (12) comprises a pressurized container (20), a gas generating material stored under pressure in the container (20), and an igniter (36) for igniting the gas generating material in the container. The gas generating material comprises an oxidizer and a fuel. At least a major portion of the oxidizer is nitrous oxide in a liquid-gas state. At least a major portion of the fuel is polyvinyl alcohol in a porous, molded solid state (64). A portion of the liquid nitrous oxide is absorbed into the pores of the molded polyvinyl alcohol (64). The gas generating material upon combustion produces a combustion product consisting essentially of carbon dioxide, nitrogen, and water.
