Solid Oxide Fuel Cell Materials

A fuel cell is a battery-like system that uses hydrogen and oxygen to generate electricity by an electrochemical reaction. Similar to other batteries, the fuel cell consists of two electrodes (anode and cathode) and an electrolyte (Figure 1).

In Solid Oxide Fuel Cells (SOFCs), the cathode and the anode are made from porous ceramic materials and the electrolyte consists of a dense oxygen ion conducting ceramics. This allows SOFCs to operate at high temperatures, around 1,000°C (1,830°F), and to reform hydrocarbons internally, thus enabling the use of natural gas or reformed diesel as fuel.1

The high-temperature operation places rigorous durability requirements on cell components. Therefore, development of low-cost materials with high durability at high temperatures is the key technical challenge for SOFC technology.2

Aldrich Materials Science offers a variety of materials that can be used for the preparation of cathodes, anodes, and electrolytes for SOFC applications, as seen in the tables below. Our product portfolio includes a variety of Yttria Stabilized Zirconia (YSZ), Lanthanum Strontium Manganite (LSM) and Gadolinium doped Ceria (GDC), and other ceramic materials specifically designed for SOFC applications.
