Assessment
Assessment strategy
Teaching takes place mainly in the lecture sessions where the principles are explained and illustrated by examples and relevant applications. Some lectures will be given by an industrial expert on fuel cells to provide a commercial perspective on the technology. Students are expected to learn material through the use of web-based material, by self-study and by problem solving during the lectures/tutorials. Students will carry out an assignment to suggest a suitable fuel cell for a specific application. The corresponding report will be marked and feedback given. The students will also assessed by a 2 hour written examination at the end of the module.
Individual coursework based on experimental demonstration, the students have to produce a one page paper that includes:
1) Brief introduction on the topic
2) Experimental details
3) Results and discussion
4) Conclusions
5) References
For the individual research or problem solving activity, students should be able to present the highlight of the proposed research activity or solve a problem, an example could be:
Question 1) A manufacturer of PEM fuel cells requires the membrane electrode assembly to be fully characterized. Describe the techniques which should be used. Give examples which show techniques for: a) membrane area resistance, b) active Pt electrode area. Relate a) to the stack voltage and b) to the Pt loading degree of utilization.
Question 2) A new energy efficient building is planned and it is suggested that light energy incident on roof mounted solar cells is used together with an electrochemical energy storage system. Provide a general overall design for such a hybrid system. a) specify the types of device, b) explain their principles of operation c) summarize previous experience providing references.
Deadlines:
Deadlines for the course works are one week after they have been assigned. Students are expected to ask about the procedure or any question related to the course work within the week. Penalties for
late handle in are applicable according to the course book.
Feedback: Written feedback is given for each course work, normally within a week
