Fferent values with the fuel utilization factor. When the cell operates as a fuel cell, the distinct values with the fuel utilization element. When the cell operates as a fuel cell, the larger the fuel utilization factor, the higher the temperature of with the cell, what ever operathigher the fuel utilization aspect, the larger the temperature the cell, what ever operating density existing is viewed as. The result might be justified analyzing the power balance. ing density present is regarded. The result may be justified analyzing the energy balance. As a matter of truth, the higher the fuel utilization factor, the greater the level of of2 H2 As a matter of reality, the greater the fuel utilization issue, the higher the amount H rereacting. As a consequence, within this case, a greater quantity of heat can also be released by the acting. As a consequence, in this case, a greater volume of heat can also be released by the exoexothermic procedure. thermic approach. On the other hand, when the cell operates as an electrolyzer, the Evernic Acid MedChemExpress opposite trend is detected as far as the density present is under a value of 854 mA/cm2 . The truth is, as anticipated, the higher the reacting H2 O, the lower the cell temperature. This trend is as a result of the truth that these electrochemical reactions are endothermic. The temperature difference within this case is reduce than the preceding case, and it decreases to 0 when a worth of existing density of about 854 mA/cm2 is reached. For greater values of your existing density, the opposite trend happens. The reason is that, within this case, the efficiency of your cell swiftly decreases due to the higher operating temperature. As soon as the threshold worth of current density isEnergies 2021, 14,12 ofEnergies 2021, 14, x FOR PEER REVIEWexceeded, the escalating of H2 production can no longer compensate for the trans-4-Carboxy-L-proline web rising of absorbed power.13 ofFigure 6. Temperature of the cell as aafunction of density existing for diverse fuel utilization variables Figure six. Temperature with the cell as function of density present for diverse fuel utilization components for the fuel cell mode (a) plus the electrolyzer mode (b). for the fuel cell mode (a) as well as the electrolyzer mode (b).However,the cell the cell generally operate inside a distinct rangeopposite trend is As a consequence, when need to operates as an electrolyzer, the of existing density detected as an optimal operation. Foris beneath a this parameter out of.the fact, asfield of the to attain far because the density existing values of worth of 854 mA/cm2 In linear anticipated, the higher the reacting conversion efficiency is very low. In addition, when the temperature polarization curve, the H2O, the reduced the cell temperature. This trend is as a result of the fact that these electrochemical degradation of your cell occurs significantly more rapidly. The selected existing in the cell is also higher, the reactions are endothermic. The temperature distinction within this case is reduced than the preceding case, and it decreases to 0 when a2 , whereas for the SOEC, density variety for the SOFC is in between 400 and 1400 mA/cm worth of current density of about 854 mA/cm2 is .reached. For higher values from the present density, is doable to it can be 300100 mA/cm2 By means from the style parameters of your cell, it the opposite trend occurs. The reason is that,energy that can be supplied by the PV field or demanded by decide the selection of electric in this case, the efficiency of the cell swiftly decreases as a consequence of the higher operating temperature. Once the threshold worth of present density is exthe loa.
