ABSTRACT
This chapter introduces the concept of producing fuel for hydrogen-powered vehicles using combined heat, hydrogen, and power (CHHP) systems based on stationary high-temperature fuel cells, which also provide electricity and heat to buildings. In addition, it explores the factors affecting the
