The Heat Balance

In this publication, in addition to focusing on the engineering component in creating our own test bench for trying various modes and the overall performance of solid polymer fuel cells with electric power of more than 2 kW, the features of the result of the operation of a liquid-cooled fuel cell in the field of heat transfer are displayed. It is known that its performance and service life depend on a properly tuned water and thermal balance of the fuel cell. The problem area is described in the insufficient moisture content of the supplied air to the fuel cell and the excess heat in the fuel cell. In this case, the negative consequence is that additional resistance to the rate of the electrochemical reaction is created, as a result of which the generated power decreases. A possible way to solve this problem is proposed: so, according to the heat balance equation, by increasing the temperature difference between the incoming and outgoing heat carrier, more heat energy can be removed. The temperature difference was achieved using a water-air radiator. The increased removal of thermal energy allowed the condensation of part of the moisture inside the fuel cell, maintaining the humidity and conductivity of the membrane, but not allowing flooding of the channels with liquid water, which otherwise could lead to a decrease in performance. During the tests, it was possible to increase the removed power by 321 w, which is 8.4% in excess of the maximum power. Based on the obtained experimental results, dependencies were constructed that are expressed by the current-voltage characteristic, power curve, the amount of heat removed by the water from the fuel cell, and a graph of the change in water temperature at the inlet and outlet of the fuel cell at various stages of operation.

The present work consists of a series of studies with regard to the structure and charge transport in solid polymer electrolytes (SPE) prepared using various new bis(trifluoromethanesulfonyl)imide (TFSI)-based dianionic dilithium salts in crosslinked low-molecular-weight poly(ethylene glycol). Some of the thermal properties (glass transition temperature, differential molar heat capacity) and ionic conductivities were determined for both diluted (EO/Li = 30:1) and concentrated (EO/Li = 10:1) SPEs. Trends in ionic conductivity of the new SPEs with respect to anion structure revealed that while for the dilute electrolytes ionic conductivity is generally rising with increased length of the perfluoroalkylene linking group in the dianions, for the concentrated electrolytes the trend is reversed with respect to dianion length. This behavior could be the result of a combination of two factors: on one hand a decrease in dianion basicity that results in diminished ion pairing and an enhancement in the number of charge carriers with increasing fluorine anion content, thereby increasing ionic conductivity while on the other hand the increasing anion size and concentration produce an increase in the friction/entanglements of the polymeric segments which lowers even more the reduced segmental motion of the crosslinked polymer and decrease the dianion contribution to the overall ionic conductivity. DFT modeling of the same TFSI-based dianionic dilithium salts reveals that the reason for the trend observed is due to the variation in ion dissociation enthalpy, derived from minimum-energy structures, with respect to perfluoroalkylene chain length.
