This patent describes a fuel cell stack. It comprises a plurality of fuel cells disposed in stacked relationship to define a power generating portion of the stack; a plurality of cooling plate assemblies interspersed throughout the power generating portion; a thermal and electrical insulating plate disposed at each end of the stack adjacent to and in face-to-face relationship with endmost fuel cells at opposite ends of the stack; a pressure plate disposed at each end of the stack outwardly of each of the insulating plates; auxiliary cooling plate assemblies disposed at each end of the stack and sandwiched between the respective insulating plate and pressure plate at each end of the stack; means for concurrently delivering temperature-controlling coolant to the cooling plate assemblies in the power generating portion of the stack and to auxiliary cooling plate assemblies.
