Advances in Materials for Solid Oxide Fuel Cells

As with all types of fuel cells, a Solid Oxide Fuel Cell (SOFC) is capable of efficiently transforming chemical energy into electrical energy.

Materials for Clean H2 Production from Bioethanol Reforming

Hydrogen is one of the most important resources in providing food, fuel, and chemical products for our everyday life. Sustainable catalytic hydrogen production from bioethanol has gained significant attention in recent years due to globally diminishing fossil fuel supplies, which have necessitated the search for new chemical feedstocks.

Questions

  1. 酸化セリウムnanopowder（544841）を水に分散させると、透明な黄緑色の均一な分散液になりますでしょうか？

    1 answer

    1. This product is available as a 10% dispersion in water under product number 643009. The appearance is an off-white liquid. The clarity is not a specification. However, this material is insoluble in water and is not expected to be a clear solution. Note that product 289744 is an unrelated dispersion of Cerium (IV) oxide in acidified water. The appearance of this item is listed as a yellow-orange liquid. Please see the links below to review a sample or lot-specific Certificate of Analysis for each item.
