ADVANCED ELECTROCHEMICAL SYSTEMS - 2020/1

Module Overview

Electrochemical energy systems play an increasingly important role in our changing energy landscape, as they provide low-carbon alternatives to the current fossil fuel based systems. The development of these electrochemical energy systems is emergent. The training for next-generation engineers with adequate knowledge and skills in this area is highly demanded, to meet the requirement from industry, and lead the development of the future technologies. Consequently, the module intends to introduce to students the scientific fundamentals of the electrochemical systems, and the working principles of several different electrochemical systems including fuel cells, electrolysers, batteries and supercapacitors, to equip the students with knowledge of the electrochemical systems, and enable them to select suitable technologies for particular applications.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

• Understanding of scientific fundamentals of electrochemical systems and working principles of different types of electrochemical devices, as well as the ability to formulate and solve practical problems related to fuel cells, electrolysers, batteries and supercapacitors in the final examination. The coursework tests and amplifies awareness and ability to formulate and solve a practical problem in electrochemical systems.

Thus, the summative assessment for this module consists of:

• Coursework – 40%, 15 hrs (LOs 2, 3, 4)

• Examination – 60%, 2 hrs (LOs 1, 2, 4, 5)

Formative assessment and feedback

• Formative verbal feedback is given during in-class problem solving and discussion sessions.

• Formative feedback on coursework is given verbally and available on SurreyLearn to provide feedback on understanding of the electrochemical energy systems and respective problem formulation and solution.

Module aims

• • Advanced knowledge and practical skills needed for a professional career in the energy industry, renewable energy industry, local and national governments setting energy strategies, research and development in energy technologies.
• • A systematic understanding and critical awareness of the importance of the electrochemical technologies in energy applications;
• • A sound understanding of the fundamental principles, operation requirements, design criteria and engineering applications of electrochemical technologies such as batteries, fuel cells, supercapacitors and electrolysers.
• • Specialist knowledge, technical expertise and research skills for further research in energy and environment systems and technologies.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

• Introduce principles electrochemical systems and different technologies in general through theory and worked examples. This is mainly delivered through lectures and in-class problem solving, as well as group discussions within the class.

The learning and teaching methods include:

• 3 hours lecture per week x 11 weeks

• 2 hours revision lectures

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
