“…A few research studies [4,24,25] have reported the numerical simulation on temperature distribution in a single PEFC, which is operated at a relatively higher temperature than usual. However, only a few papers [4,24] have investigated the temperature distribution near the interface between the PEM and catalyst layer at the cathode, which is defined as a reaction surface in this study, excluding other studies by the authors [26][27][28][29]. The authors' studies [26][27][28][29] have investigated the effect of PEM's thickness and GDL's thickness on the distribution of the temperature at the reaction surface (T react ), in a cell of the PEFC at higher temperature, i.e., 90 • C or 100 • C, by a model using the experimental temperature-distribution data obtained by means of a thermograph.…”

“…The aim of this study is to analyze the effect of separator thickness on the distribution of T react in a single PEFC, with the changing flow rates and relative humidity (RH) of the supply gases as well as the initial operation temperature (T ini ), from the general operation temperature of 80 • C to a higher temperature, i.e., 90 • C and 100 • C. The combination of thin PEM and thin GDL is adopted for analysis, since previous studies by the authors [26][27][28][29] have clarified that using thin PEM and thin GDL at the same time is effective to attain higher power-generation performance of a PEFC operated at a higher temperature than usual. The temperature distributions on the separator's back, of a cell of the PEFC, have been measured by means of a thermograph and used as the boundary-condition data for the heat-transfer model developed by the authors [30,31].…”

“…According to the previous studies carried out by the authors [26][27][28][29], a 1D multi-plate heat-transfer model, which uses the temperature data of the separator's back, measured by the thermograph under a power-generation condition, has been presented. A single PEFC is composed of the PEM, catalyst layer, MPL, GDL, and separator.…”

“…A single PEFC is composed of the PEM, catalyst layer, MPL, GDL, and separator. The heat-transfer model developed by the authors [26][27][28][29] has assumed that the heat flows through multi-plates of these cell components. The temperature at the interface between the PEM and the catalyst layer on the cathode, i.e., T react , is calculated by the heat-transfer model [26][27][28][29].…”

The New Energy and Industry Technology Development Organization (NEDO) road map (Japan, 2017) has proposed that a polymer electrolyte fuel cell (PEFC) system, which operates at a temperature of 90 °C and 100 °C, be applied for stationary and mobility usage, respectively. This study suggests using a thin polymer electrolyte membrane (PEM) and a thin gas diffusion layer (GDL), at the same time, to achieve better power-generation performance, at a higher temperature than usual. The focus of this paper is to clarify the effect of separator thickness on the distribution of temperature at the reaction surface (Treact), with the relative humidity (RH) of the supply gasses and initial operation temperature (Tini), quantitatively. In this study, separator thickness is investigated in a system using a thin PEM and a thin GDL. Moreover, this study investigates the difference between the maximum temperature and the minimum temperature obtained from the distribution of Treact as well as the relation between the standard deviation of Treact − Tini and total voltage, to clarify the effect of separator thickness. The impact of the flow rates of the supply gases on the distribution of Treact is not large, among the investigated conditions. It is noticed that the temperature distribution is wider when a separator thickness of 2.0 mm is selected. On the other hand, it is observed that the temperature increases along with the gas flow through the gas channel, by approximately 2 °C, when using a separator thickness between 1.5 mm and 1.0 mm. The impact of the RH on the distributions of Treact − Tini is larger at Tini = 100 °C, when a separator thickness of 1.0 mm is selected. It is revealed that the wider temperature distribution provides a reduction in power-generation performance. This study proposes that the thin separators, i.e., with a thickness of 1.5 mm and 1.0 mm, are not suitable for higher temperature operation than usual.

Polymer Electrolyte Fuel Cell (PEFC) is desired to be operated over 90℃ during the period from 2020 to 2025 in Japan. The aim of this study is to clarify the impact of microporous layer (MPL) on the temperature profile of interface between polymer electrolyte membrane (PEM) and catalyst layer at the cathode (i.e., the reaction surface) in a single PEFC with an initial temperature of cell (Tini) from 80℃ to 100℃. An 1D multi-plate heat transfer model based on temperature data of separator measured using thermograph in power generation was developed to evaluate temperature of the reaction surface (Treact). This study investigated the effect of MPL, Tini, flow rate and relative humidity of supply gas on Treact distribution. As a result, it is found that the impact of flow rate of supply gas on Treact distribution is little irrespective of MPL, Tini and relative humidity of supply gas. When MPL is not coated, Treact -Tini is higher by 2℃ -3℃ and relatively flat compared to MPL coating condition and Treact -Tini with MPL is increased by 1℃ from the inlet to outlet of cell irrespective of Tini and relative humidity of supply gas. In addition, it is revealed that Treact -Tini with MPL is the highest when the relative humidity of supply gas is 40 %RH at the anode and 40 %RH at the cathode, which is the lowest relative humidity condition in this study.
