<p>The present invention relates to a mixed gas generating device and has an object to provide a mixed gas generating device capable of generating CO and H 2 with favorable energy efficiency. An energy efficiency characteristic line 10 of electrolysis with respect to a generation ratio between CO and H 2 (CO / H 2 ) becomes a curve projecting downward. Thus, electrolysis is executed not at an operation point A where CO / H 2 = 1/2 is given but in a divided manner at an operation point B and an operation point C. However, the electrolysis time is divided into electrolysis time periods such that the generation ratio of a mixed gas becomes CO / H 2 = 1/2 after the electrolysis is executed with the respective generation ratios. As a result, energy efficiency in the vicinity of an operation point D higher than the operation point A can be obtained.</p> |
