“…The performance of a polymer electrolyte membrane fuel cell (PEMFC) is depending on the materials and cell design, and on the operating conditions used. Once a given cell design is specified, the operating conditions can largely influence not only the cell performance but also other major parameters such as durability , and the final cost of operation. Pressure is obviously among the possible operating conditions to be defined, where it is known that an increase of the operating pressure is beneficial for increasing the cell voltage, as a higher open circuit voltage (OCV) is obtained as well as less activation polarization losses due to higher partial pressures of the reactants .…”

The operating pressure has a significant influence in the performance of a fuel cell, as it influences the output voltage via activation, ohmic, and mass transport losses. In this work, experiments with a 50 cm2 polymer electrolyte membrane (PEM) fuel cell with serpentine flow field have been carried out to investigate the effects of the operating pressure on the cell performance, with a particular analysis of the liquid water distribution within the cell. A comprehensive matrix of anode and cathode pressures was analyzed, varying the anode and cathode pressure from 1.25 to 2.00 bar (abs). Neutron imaging was used to determine the liquid water distributions within the cell for each operating condition and to assess the effect of the different operating pressures. Cell voltage was also monitored during the experiments and included in the analysis. A certain accumulation of liquid water was found in the cathode channels, were the overall liquid water accumulation was found to be more significant for higher pressures. This dependence on the operating pressure was more pronounced for lower current densities, and it was more significant for cathode pressure than for anode pressure.

Proton exchange membrane fuel cells (PEMFCs) have become the center of attention for energy conversion in many areas such as automotive industry, where they confront a high dynamic behavior resulting in their characteristics variation. In order to ensure appropriate modeling of PEMFCs, accurate parameters estimation is in demand. However, parameter estimation of PEMFC models is highly challenging due to their multivariate, nonlinear, and complex essence. This paper comprehensively reviews PEMFC models parameters estimation methods with a specific view to online identification algorithms, which are considered as the basis of global energy management strategy design, to estimate the linear and nonlinear parameters of a PEMFC model in real time. In this respect, different PEMFC models with different categories and purposes are discussed first. Subsequently, a thorough investigation of PEMFC parameter estimation methods in the literature is conducted in terms of applicability. Three potential algorithms for online applications, Recursive Least Square (RLS), Kalman filter, and extended Kalman filter (EKF), which has escaped the attention in previous works, have been then utilized to identify the parameters of two well-known semi-empirical models in the literature, Squadrito et. al and Amphlett et. al. Ultimately, the achieved results and future challenges are discussed.

Abstract. This paper focuses on the thermal modelling of a CHP system based on Proton Exchange Membrane Fuel Cell (PEMFC) by experimental analysis and analytical relationships. To this end, there have been carried out several experimental tests on a PEMFC 600 W of electrical power in order to obtain the necessary data for thermal modelling and its subsequent validation. Once made the experimental analysis, data obtained have been used to develop the thermal model of the stack of the fuel cell as well as the entire temperature management system, by implementing various analytical relationships in the MATLAB/Simulink environment.The model obtained has allowed to characterize the thermal behaviour of the fuel cell to different profiles of electrical and thermal energy demand, with a minimum and maximum relative error in the temperature of the stack of 3.77% and 11.05%, respectively.
