Abstract
An internal coolant circulation system and method of homogenizing waste heat in a fuel cell stack using homogenous thermal coolant cycling is disclosed. The method includes operating a fuel cell stack, distributing a coolant through the fuel cell stack, terminating operation of the fuel cell stack, retaining the coolant in the fuel cell stack and circulating the coolant throughout the fuel cell stack.
