Abstract

A gas generating apparatus generates hydrogen having carbon monoxide concentration of 0.1% or less by reacting hydrogen carbide and water together without requiring a platinum catalyst. The gas generating apparatus includes a gas instantaneously-heating mechanism that instantaneously heats a source gas, and a catalyst vessel connected to the gas instantaneously-heating mechanism and containing a catalyst. A high-temperature heated source gas beam generated by the gas instantaneously-heating mechanism, which contains hydrogen carbide and water, is caused to collide with the catalyst to generate a gas. Heat of the source gas is transmitted to a catalyst surface because of the absence of a stagnation layer, and a non-equilibrium reaction efficiently proceeds on the catalyst. Hydrogen can be extracted with a low-cost ruthenium catalyst.
