France to Denpasar, transit in Shanghai for 11 hours

Yes, you definitely are. Your itinerary is undeniably eligible for 24 hour visa free transit and you do not need any kind of visa. Just one detail... If you plan to exit the airport in Shanghai, you will immediately approach transit counter (desk) upon your landing where you will apply for a temporary entry permit. This application is free of charge. You have to know that the issuing of the permit is based entirely on discretionary decision of airport authorities on the day, so you can expect both outcomes. However, I would say that your chances to be granted a permit are quite high because of the length of your layover.
