Optimal temperature control in PEM fuel cells

Performance Improvement by Temperature Control of an Open‐Cathode PEM Fuel Cell System

“…T im e described by equation (2). Hence, the temperature change of the stack over time as a function of generated and removed heat can be described with the following set of equations:…”

“…However, modeling and controlling PEM fuel cell based systems is a particularly challenging task due to the interactions between physical phenomena of different nature and the presence of nonlinear structures [1]. The work presented by [2] shows a first approach of how to control temperature of PEM fuel cells. However, optimal thermal management related to humidification is still a crucial issue in every PEM fuel cell based system.…”

An adaptive fuzzy logic controller (AFLC) for PEMFC fuel cell

“…However, the performance, reliability, cost and stability for the present PEMFC technology are not enough to replace internal combustion engines. Thereby comprehensively considering above fundamental problems, fuel cells have to be improved their performance and be reduced their cost in order to achieve best performance [23].…”

“…One of the significant challenges in control algorithms is that many parameters such as operating temperatures, pressure and flow rates of fuel and oxidant gases and so on affect the performance of PEMFC [3]. However, fuel cell output voltage is changed in different loads.…”

Control and integration of a PEMFC mobility car

“…Vega-Leal et al [1] optimized the net power of a PEMFC by controlling the air and hydrogen flow rates. Luis et al [2] designed controllers to operate the PEMFC at an optimal temperature in different loads. Wang et al [3][4][5][6] designed robust controllers to regulate the oxygen and hydrogen flow rates to provide a constant voltage or current and to improve the efficiency.…”
