Waste heat recovery in automotive engineering is part of the sustainable energy effort to optimize energy utilization. For vehicles running on hydrogen fuel cells, the potential of heat recovery is perceived to be limited due to the low quality energy generated from the fuel cell stack. It has been established in fuel cell operation that increasing the inlet hydrogen temperature improves the conversion efficiency through higher kinetic reaction rates. A fuel cell power plant for a mini vehicle that will be competing in Shell Eco Marathon Asia 2014 was studied to identify the potential energy recovery limits for an improved power plant design with regenerative hydrogen pre-heater. Using modeling approach for fuel cell power generation and efficiency relationships, the first-order waste energy potential was identified based on test bench studies on the electrical and thermal power relationship of the fuel cell stack performance. The corresponding result is then mapped to a driving cycle to investigate the thermal power generated during the race in both aggressive and passive driving cycle. The energy recovery potential for 4 laps course under aggressive and passive driving cycle are 529 kJ and 501.8 kJ consecutively. The mean thermal powers are 485 W and 410 W respectively which is the reference energy for extended heat exchanger design purposes.

“…Thus, the best solution can be achieved considering the size and the cost of the powertrain. The mathematical equations proposed by the authors [12][13][14][15] to calculate the hydrogen consumption of the fuel cell stack. The molar hydrogen consumption of the fuel cell is given in equation 1 [12][13];…”

In the study, we proposed a new formula for the hydrogen consumption of fuel cell under non-constant current behavior. We used supercapacitors as auxiliary energy source to form a hybrid system and change the current behavior of the fuel cell. We performed hybrid system tests for different supercapacitor values. We extracted the fuel cell current, voltage, hydrogen consumption for each configuration. We compared the measured values and expected values from known equations. We see that, results from hydrogen consumption equations does not match the hybrid system hydrogen consumption. Finally, we proposed a new formula for hydrogen consumption including the current gradient and current peak value for hybrid systems.
