OVERVIEW

This course (completely in English) shows the fundamental know-how of fuel cells and distributed generation systems (thermodynamics and component performance): different typologies, layouts, technological and environmental aspects. Different small size systems are considered for distributed generation applications. Special attention is devoted to combined heat and power generation including laboratory experiences.

AIMS AND CONTENT

LEARNING OUTCOMES

The purpose of this teaching unit is to provide the students with fundamental know-how related to fuel cells and to the concept of distributed generation systems. Attention is mainly focused on thermodynamic theory and component performance. Fuel cells are presented putting emphasis on different technology types, plant layout integration, technological and environmental aspects. Special attention is devoted to hybrid systems including fuel cells starting from plant layouts to design and integration aspects. This unit also provides students with basic knowledge and operative elements to design different small size power systems for applications in distributed generation grids. For this part of the unit, special attention is devoted to combined heat and power generation. Laboratory visits are also included in the teaching activities to provide the students with technological aspects related to pratical experiences.

AIMS AND LEARNING OUTCOMES

The attendance and active participation at the proposed teaching activities (lessons, exercises and laboratory activities) and the individual study will allow the student to:

- know the basic aspects related to different fuel cell types (performance and operative issues);

- know the characteristics of hybrid systems (plant solutions, performance, etc.);

- know the aspects related to simulation and control of fuel cell based systems;

- understand the distributed generation systems;

- understand the distributed generation systems with co-generation and/or trigeneration;

- apply the thermodynamic concepts to the performance calculations;

- identify and analyse the main plant components;

- know aspects related to fuel-based laboratory plants development and utilization.

TEACHING METHODS

The course is composed of: 54 hours including classroom lessons, exercises and laboratory experiences. The exercise hours will be carried out by the teacher with the following approach: summary introduction on the contents related to the classroom lessons and development of exercises. At least 1 seminar will be included considering external teachers.

Students who have valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the instructor and with Professor Federico Scarpa (federico.scarpa@unige.it), the Polytechnic School's disability liaison.

SYLLABUS/CONTENT

• Fuel cells (basic structure, brief history, technological status, cost considerations); fuel cell types (polymeric, alkaline, phosphoric acid, molten carbonate, solid oxide); fuel cell electrochemistry (ideal and losses).
• Fuel cells: influence of main operative properties (pressure and temperature), materials, performance, fuel processing (external and internal reforming).
• Hybrid systems with high temperature fuel cells (MCFC; SOFC).
• Simulation, emulation and protypes of systems with fuel cells.
• Control of systems with fuel cells.
• Distributed generation systems: basic aspects, plant management and stirling engines.
• Distributed generation systems: co-generation and tri-generation.
• Laboratory activities (technical visits and experimental experiences) on fuel cell systems and distributed generation plants.

RECOMMENDED READING/BIBLIOGRAPHY

All the slides used during the lessons and other teaching materials will be available on aul@web. In general, lesson notes and the aul@web teaching materials are enough for the successful exam preparation.

Students not attending the lessons (although the active participation at the lessons is strongly recommended) are suggested to use the aul@web teaching material. In case of doubts on these documents, please contact the teacher by e-mail: mario.ferrari@unige.it.

The following books are suggested as support (the exam can be successfully passed without reading these books):

• Fuel Cell Handbook (Seventh Edition), US Department of Energy, Morgantown, WV (USA), 2004 (available on line).
• Ferrari M.L., Damo U.M., Turan A., Sanchez D., Hybrid Systems Based on Solid Oxide Fuel Cells: Modelling and Design, Wiley, July 2017 (available in the library).
• R. Della Volpe, “Macchine”, Liguori Editore (available in the library).

EXAMS

EXAM DESCRIPTION

The exam is composed of an oral test on all the topics presented and discussed during the course (exercises excluded).

2/3 exam days will be available in the winter session and 3/4 for the summer session (verify on the web tool https://servizionline.unige.it/web-studenti2/en/#/prenotazione). No additional exam days will be carried out, except for the students that terminated their lessons. So, these students can contact the teacher by e-mail (mario.ferrari@unige.it) to schedule a possible exceptional exam day.

To participate at this oral test, it is necessary to do the registration (at least 5 days in advance) on the web tool https://servizionline.unige.it/web-studenti2/en/#/prenotazione.

Students with a certified learning disability (DSA), a disability, or other special educational needs are invited to contact the instructor at the beginning of the course to discuss teaching and examination arrangements that, while respecting the learning objectives of the course, take individual learning needs into account and provide appropriate accommodations.
Please also note that requests for exam accommodations or exemptions must be submitted using the form available at this link https://modulionline.unige.it/richiesta-adattamenti#no-back, to the course professor, the DIME contact person (federico.scarpa@unige.it), and the relevant office (inclusione.studenti@info.unige.it) at least seven working days before the examination, in accordance with the guidelines available at this link https://unige.it/disabilita-dsa/richiesta-servizi

ASSESSMENT METHODS

The achievement of the learning results will be carried out with oral questions that can be supported by writing activities (on the blackboard or a paper sheet).

These questions will evaluate not only the student's knowledge, but also the analysis capability of problems related to fuel cell based systems and distributed generation and the presentation with a right terminology. The student can be asked to design plant schemes, to analyse the system behaviour on the main thermodynamic planes, and to carry out design calculations in agreement with what presented during the lessons.
