Patent ID: 7189371

Claim:
A fuel reforming system comprising a fuel reformer for generating a reformed gas containing hydrogen by using a gas containing vapors of a gas fuel or a liquid fuel and a gas containing oxygen, a mixer of vapors of the gas fuel or the liquid fuel and the gas containing the oxygen, a supplier of vapors of the gas fuel or the liquid fuel into said fuel reformer through the mixer, a supplier of the gas containing the oxygen into said fuel reformer through the mixer, and a controller of a first flow rate of the vapors of the gas fuel or the liquid fuel supplied into said fuel reformer and of a second flow rate of the gas containing the oxygen supplied into said fuel reformer, further comprising: a detector of the first flow rate of the vapors adapted to obtain a detected first flow rate; a detector of the second flow rate of the gas adapted to obtain a detected second flow rate; and a temperature detector of at least one of the vapors of the gas fuel or the liquid fuel supplied into said fuel reformer, the gas containing the oxygen supplied into said fuel reformer, and a mixture of vapors of the gas fuel or the liquid fuel and the gas containing the oxygen, and a controller configured to correct a ratio of the first flow rate of the vapors to the second flow rate of the gas depending on the output of said temperature detector, thereby obtaining a corrected ratio, determine the second flow rate to be supplied to the supplier of the gas containing the oxygen according to the detected first flow rate and the corrected ratio, and adjust a flow rate of the gas containing the oxygen into said fuel reformer by controlling the supplier of the gas containing the oxygen according to the determined second flow rate.
