Topic: Analytical Modeling of the Polarization Curves of a 40-W Fuel Cell Stack 

Author: Shaker Haji 

Institution: Department of Chemical Engineering, College of Engineering, University of Bahrain 

 

Location: Manama, Kingdome of Bahrain 

Abstract 

In this study, the performance of a bench scale fuel cell stack, run on hydrogen/air, is measured experimentally. The experimental data, obtained from the 40-watt proton exchange membrane fuel cell (PEMFC), are used in estimating the parameters of a completely analytical model that describes the polarization curve. The analytical model consists of the three fundamental losses experienced by a fuel cell, namely: activation, ohmic, and concentration losses. The current loss is also considered in the model. While the Tafel constants, ohmic resistance, and the concentration loss constant are estimated through multiple linear regression analysis, the limiting current density and the current loss are obtained through measurements. The model and its estimated parameters are used to demonstrate the proportions of the three fundamental losses and to predict the fuel cell delivered power density as a function of the current density. The theoretical equations derived in the literature, which model fuel cell performance, are found to reasonably fit the obtained experimental data. 

Keywords: PEMFC, Performance Modeling, Polarization Curve, i-V curve, Fuel Cell Losses.

Abstract 

De nos jours, le réchauffement climatique est au centre de toutes les problématiques mondiales.  Les  ressources  fossiles  que  nous  utilisons,  en  plus  de  s’épuiser,  polluent  énormément.  Le  monde  cherche  donc  à  se  tourner  vers  l’utilisation  d’énergies renouvelables. Cependant, aussi prometteuses qu’elles soient, les énergies renouvelables (issues  du  rayonnement  solaire,  du  vent,  de  l’eau)  ne  proposent  pas  d’énergie  à  la  demande  car  dépendent  de  nombreux  paramètres  tels  que  la  météo  au  moment  dit, l’heure de la journée et le moment de l’année. Il se pose donc un problème de stockage de  ces énergies pour réussir à se libérer totalement des énergies fossiles. C’est dans ce  cadre  que s’est constitué le projet européen ​Electrons to high value Chemical products (E2C)​. Pour la partie située au sein de l’Université de Lille, le projet consiste à étudier la combinaison  de  plusieurs  énergies  renouvelables  afin  d’en  sortir  une  production  la  moins  variable  possible,  un  stockage  du  surplus  d’énergie  vers  des  batteries  et  des bouteilles d’hydrogène grâce à l’électrolyse de l’eau. Les avantages de ce mode de stockage sont les suivants : en l'associant au stockage par batterie  disponible  dans  l'armoire  de  commande  de  la  plateforme,  on  obtient  un  gain non seulement en autonomie mais aussi en disponibilité en énergie.

Topic: Education & Research with a Flexible Hybrid RE System - Case Study

Institution: Brandenburg University of Technology Cottbus (BTU Cottbus, Germany), Chair of Power Plant Technology

Location: Cottbus, Germany

Client Request:

Expand Power Generation  

Education & Research into Renewable Energy Systems

BTU Cottbus approached Heliocentris with the goal of expanding their Power Generation Programs to include extensive teaching and research in the area of Renewable Energies.  The Chair of Power Plant Technolo-gy saw great demand for the integration of renewable energy systems into their programs and set a primary focus on power generation and the optimization of grid-tied renewable energy systems.  They wanted to couple their extensive knowledge of traditional energy systems based on coal and biomass, with renewable energy systems to create better and more efficient energy systems. This was to be achieved by providing students hands-on experience with a complex renewable energy laboratory.

Topic: Interdisciplinary Minor In Hydrogen Technology at Michigan Techlogical University

Location: Michigan, USA

The search for alternative energy sources is an area that has received great attention in the last few years, beginning with the January 2003 State of the Union address by President George W. Bush, approving federal funding for hydrogen fuel cell research for passenger vehicles. Similar announcements were made by state governors, most notably Michigan Governor Jennifer Granholm, stating “not only will we build these cars in Michigan, our Automotive Technology Corridor will help develop the fuel cell technology those cars will run on.”   

Inherent within the nation’s initiative should be the development of educational programs related to fuel cells and other aspects of the hydrogen economy, including advantages and disadvantages. This is important since hydrogen has been proposed for use in transportation applications as a replacement fuel for gasoline, with fuel cells replacing the internal combustion engine. As such, the Energy Policy Act of 2005 was passed by the 109th Congress1 as Public Law 109–58. This bill contained the Spark M. Matsunaga Hydrogen Act of 2005 (cf Sections 801-816). One aspect of this bill was to fund the development of university education programs. These programs are described in more detail in the Department of Energy Multi-Year Research, Development, and Demonstration Plan.
