"The book introduces the theory of fuel cells and sliding-mode control. It contextualises PEMFCs both in terms of their development and within the hydrogen economy and today’s energy production situation as a whole. It then discusses fuel-cell operation principles, the mathematical background of high-order sliding-mode control and to a feasibility study for the use of sliding modes in the control of an automotive fuel stack. Part II presents experimental results of sliding-mode-control application to laboratory fuel cells and deals with subsystem-based modelling, detailed design, and observability and controllability. Simulation results are contrasted with empirical data and performance, robustness and implementation issues are treated in depth. Possibilities for future research are also laid out."

"Glukosa oksidase pada permukaan elektroda BDD yang termodifikasi AuNP telah dibuat untuk aplikasi sel bahan bakar enzimatik (SBE). AuNP-BDD dibuat dengan cara merendam BDD termodifikasi nitrogen (N-BDD) menggunakan AuNP, sedangkan N-BDD disusun dengan menggunakan metode fotokimia pada larutan amonia dan disinari UV 254 nm. respon elektrokimia dari transfer elektron dan oksidasi glukosa pada elektroda termodifikasi telah diamati dengan tujuan untuk memfabrikasi sebuah SBE. Voltametri siklik (CV) mengamati puncak reduksi oksigen di 0,14 V pada konsentrasi glukosa yang berbeda (0,1-0,9 M) pada larutan penyangga fosfat (PBS) pada pH 7. Selanjutnya, variasi scan rate menunjukkan arus puncak memiliki nilai linear (R2 = 0.99) terhadap scan rate1/2 bahwa puncak ini dikendalikan oleh proses kontrol difusi. Sebuah SBE Model laboratorium dibangun dengan menggunakan elektroda AuNP-BDD-GOks sebagai anoda dan kalium ferrosanida-ferrisianida sebagai katoda dengan sistem terbuka. Dari studi discharge, elektroda itu ditemukan juga bekerja pada potensial optimal. Oleh karena itu, penelitian ini menyimpulkan bahwa modifikasi elektroda pada penelitian ini menjanjikan untuk aplikasi SBE.

Glucose oxidase immobilized in gold nanoparticles-modified boron-doped diamond was prepared for an application in enzymatic fuel cells (EFCs). AuNPs- BDD was prepared by immersing nitrogen-modified BDD (N-BDD) in a colloidal AuNPs, whereas N-BDD was prepared using photochemical method in an ammonia solution under UV light. The electroanalytical responses of the electron transfer and the oxidation discharge of glucose at the electrode were studied in order to build an EFC. Cyclic voltammetry observed an oxygen reduction peak at 0.14 V. The current of this peak was linear (R2= 0.99) with different glucose concentrations (0.1-0.9 M) and phosphate buffer solution (PBS) at pH of 7. Furthermore, the scan rate dependency showed that this peak was controlled by diffusion control process. A laboratory model EFC was built by mounting the anode with a potassium ferrocyanide-ferricyanide cathode in open system. From these discharge studies, the electrode was found to be well working at the optimum potential. Hence, the current study concluded that the modified electrode is a promising electrode for EFC."

"Fuel cells in the waste-to-energy chain explores the concept of waste-to-energy through a 5 step process which reflects the stages during the transformation of refuse flows to a valuable commodity such as clean energy. By providing selected, integrated alternatives to the current centralized, wasteful, fossil-fuel based infrastructure, this book explores how the concept of waste-to-energy can be constructed and developed into a realistic solution. The entire spectrum of current and future energy problems is illuminated through the explanation of the operational, integration and marketing implications of high efficiency technological solutions using the real context of developed regions such as Europe. Up-to-date reviews are provided on the status of technology and demonstration, implementation and marketing perspectives. The detailed technological information and insight gathered from over twenty years of experience in the field makes Fuel cells in the waste-to-wnergy chain a valuable resource for all engineers and researchers in the fields of energy supply systems and waste conversion, as well as providing a key reference for discussions by policy makers, marketing experts and industry developers working in energy supply and waste management."
