“…8 shows the characteristics of the cold start of the PEMFC when the BP is heated to 20, 40 and 60 ℃, namely, the dependences of the current density and temperature of the PEMFC on time, and i-V curves before freezing and after cold start. The stack is started up in the maximum power mode at a voltage of 0.5 V, which provided the optimal mode for reaching the operating characteristics [25,45]. The module was heated by a built-in heating unit, a hydrogen-air mixture was used with a hydrogen concentration in the flow of 1.2, 1.8 and 2.2 vol.%, respectively, at a BP temperature of 20, 40 and 60 ℃.…”

The paper report on the cold start of fuel cell with proton exchange membrane (PEMFC) at – 40 °C using a catalytic heating unit integrated directly into the PEMFC bipolar plates. This technical solution increases the heat transfer efficiency up to 60% due to direct contact of the membrane-electrode assembly with the heating unit, and ensure a successful cold start of the fuel cell from – 40 °C to an operating temperature of 35 °C within 6 minutes at air flow rate of 150 mL/min. The hydrogen flow rate is 45 cm3/s, which corresponds to a hydrogen concentration in the air flow of ca. 1.8 vol.%, which is below the autoignition point and ensures the safety of the proposed method. Uniform distribution of heat over the bipolar plates surface prevents dehydration and thermal degradation of the membrane electrode assembly components and improve the PEMFC performance after cold start.

“…6 But catalytic combustion induces large in-plane temperature differences, 7 and the generated water still exists in the super-cooled state. 8 In contrast to the aforementioned methods that utilize the energy in the fuel, the auxiliary heating methods employ external powers (e.g., on-board batteries), leading to higher heat production ceilings. 9 However, the commonly used coolant heating 10,11 and gas heating 12,13 methods are energy and time consuming owing to the high thermal mass of the heating media.…”

The growing interest in deploying fuel cell vehicles in heavy-duty sectors and cold regions has imposed more stringent requirements for cold start methods. The alternating hydrogen pump (AHP) method enables efficient cold starts while avoiding failure and degradation caused by freezing of super-cooled water. Herein, the sensitivity of parameters such as the alternating frequency and gas flow rate, as well as the effects of H2 supply methods and power control sequences, are explored for increasing the heating power using the model developed in Part I. With the optimized values, the heating power of AHP is tripled, enabling PEMFCs with graphite bipolar plates to start-up from -30°C to 0°C within 30 s. In addition, the superiority of AHP in terms of capability, degradation, and practical convenience is demonstrated through the comparison with state-of-the-art rapid self-heating method.
