Claim 2:
3. The computer of claim 2 wherein the at least one processor is further programmed to:
determine a waste heat based on an ideal voltage from the fuel cell stack, an actual voltage from the fuel cell stack, an actual current generated by the fuel cell stack, and a latent heat;
determine an estimated flow rate of the coolant through the coolant passage based on the pressure drop, a coefficient of laminar flow associated with the coolant, a viscosity of the coolant at the average temperature of the coolant, a coefficient of turbulent flow associated with the coolant, and a density of the coolant at an average temperature of the coolant; and
determine an estimated delta temperature associated with the pressure drop based on the waste heat, the estimated flow rate, a density of the coolant, and a specific heat capacity of the coolant.
