The strengthened regulations for atmospheric emissions from ships have caused a necessity of new, alternative power system in ships for the low pollutant emissions and the high energy efficiency. Recently, new kinds of propulsion power system such as fuel cell system, which use hydrogen as an energy source, have been sincerely considered. Fuel conversion system to hydrogen is an essential part for fuel cell ship. We have investigated thermodynamically the steam reforming characteristics of hydrocarbons and alcohols for the fuel conversion systems.

Strengthened regulations for atmospheric emissions from ships have created a need for new and alternative power systems that offer low emissions and high energy efficiency. Recently, new types of propulsion power systems, such as fuel cell systems that use hydrogen as an energy source, have gained serious consideration in applications requiring emission control. The purpose of this work is to certify the availability of solid oxide fuel cell (SOFC) systems equipped with recycled steam reforming fuel processors, and to compare their performance with that of extra steam reforming systems. The results demonstrate that the recycled steam reforming system has a slightly lower cell voltage and higher energy efficiency than the extra steam reforming system.
