Patent attributes
A hydrogen generating apparatus includes a reformer that reforms fuel and generates reformed gas containing hydrogen, a combustor that heats the reformer, an exhaust gas path which covers the surroundings of an outer wall of the reformer and through which combustion exhaust gas from the combustor flows, and a reformed gas path through which the reformed gas sent from the reformer toward the combustor flows. The reformer is arranged on a flame forming side of the combustor, and a gas flow within the reformer in a portion thereof where the gas flow contacts the outer wall of the reformer is opposed to a flow of the combustion exhaust gas in the exhaust gas path in a portion thereof where the combustion exhaust gas contacts the outer wall of the reformer.
