Part 7: Fine Ceramics Opening Up Opportunities for New Types of Energy

Fine Ceramic Materials at Work in the Heart of Residential-use Fuel Cells
Solid oxide fuel cell (SOFC) system for residential use
Fuel cells for residential use are made up of two units: a generating unit to produce electricity and a hot-water supply unit which uses the heat produced when electricity is generated. They are highly energy efficient, produce an extremely low amount of nitrogen oxide (NOX) and sulfur oxide (SOX), and emit very little carbon dioxide (CO2) รณ leading causes of climate change. As an environmentally friendly system for the home, their use is expected to spread in the future.

Cell Produced by laminating several ceramic materials. The electric power generator, where hydrogen is extracted from utility gas or propane gas fuel and made to react chemically with oxygen to produce electricity. Cell stack The collection of cells which form the heart of the fuel cell. The voltage and output are raised by connecting the cells in series. Solid oxide fuel cell (SOFC) generating unit for residential use

Understanding the Features of Fine Ceramics
Various types of fuel cells are made by using different materials for the cells at the heart of the system. Polymer electrolyte fuel cells (PEFC) using polymer electrolyte membranes are already available for residential use. However, one company has proceeded with the development of solid oxide fuel cells (SOFCs), which generate electricity even more efficiently than PEFCs. For the cell materials Kyocera uses Fine Ceramics, with their superior heat resistance and durability, and they have achieved one of the highest levels of generating efficiency in the world.
