摘要 In this paper we have considered a model of the universe filled with Generalized Cosmic Chaplygin Gas and another fluid with barotropic equation of state. We observe its role in accelerating phase of the universe by considering the mixture of these two fluid models valid from the radiation era to  for  and the radiation era to quintessence model for . The statefinder parameters describe the evolution of the universe in different phases for these two fluid models.
