WebAmongst the most common of the MEA failure modes is the poisoning of the platinum anode electrocatalyst by adsorbed carbon monoxide (CO); CO may enter the fuel cell as an impurity in the fuel (i.e. in hydrogen derived from the reformation of hydrocarbons), or if in a direct methanol fuel cell (DMFC), from fuel oxidation. Web3.2.1 Classification and merits of reversible thermochromic materials. A thermochromic material is a material that changes solar reflectance in response to temperature. The temperature at which the solar reflectance changes is called the transition temperature. Thermochromic materials are divided into two categories based on reversibility. WebCommon material responses are controlled release, color changes, morphological changes or changing the mechanical properties of the bulk material.
