The invention provides a starting control method and system of a fuel cell system and a fuel cell automobile, and relates to the field of starting control of the fuel cell system, and the fuel cell system is applied to the fuel cell automobile. The fuel cell system comprises a fuel cell stack, an air assembly, a hydrogen assembly and a heat management assembly, after a starting instruction of the fuel cell system is received, the first temperature of the air assembly is obtained; then determining a starting strategy of the fuel cell system by using the first temperature; controlling the fuel cell system to start according to the starting strategy, and determining an operation strategy of the fuel cell system by using a second temperature value collected by a second temperature sensor; and finally, controlling the fuel cell system to operate by using the operation strategy. According to the method, gas heat in the air assembly is utilized to perform heat transfer on hydrogen in the hydrogen assembly, so that the temperature of the hydrogen entering the fuel cell stack is increased, and the problem of water logging caused by relatively low hydrogen temperature is effectively relieved.
