The fuel tanks in almost all aircraft are in the wings. They have always been built that way. The designers feel, from several different angles, that it's the best place to have the fuel tanks - simple as that.
Gasoline is stored in tanks underground. The outside temperature has no effect on the temperature of the fuel stored underground.
Solar cars gain energy from the sun or wind to make fuel or power that have been stored in their batteries or fuel tanks. They use the power in their batteries or fuel tanks to run during the day!
Hydrogen can't be stored in conventional fuel tanks because it is a gas at normal temperature and pressure.
