Abstract
Combustion heaters having internal combustion chambers are located adjacent the end cells of a stack of fuel cells to directly, conductively heat the end cells during cold start-up of the stack. Similar heater(s) may also be located within the stack when cold starting under extremely cold conditions. A method of combustion thawing a fuel cell stack is described.
