An internal reforming fuel cell system wherein the reforming reaction in the cell absorbs heat from the electrochemical reaction in the cell in an amount to substantially maintain the cell at a predetermined temperature and without the need for additional cooling considerations. The excess fuel process gas from the cell is utilized such that the net utilization of the process gas of the fuel cell and utilization device exceeds about 50%.
