  • Patent number: 11173481
    Abstract: Disclosed are a metal single-atom catalyst and a method for preparing the same. The method uses a minimal amount of chemicals and is thus environmentally friendly compared to conventional chemical and/or physical methods. In addition, the method enables the preparation of a single-atom catalyst in a simple and economical manner without the need for further treatment such as acid treatment or heat treatment. Furthermore, the method is universally applicable to the preparation of single-atom catalysts irrespective of the kinds of metals and supports, unlike conventional methods that suffer from very limited choices of metal materials and supports. Therefore, the method can be widely utilized to prepare various types of metal single-atom catalysts. All metal atoms in the metal single-atom catalyst can participate in catalytic reactions. This optimal atom utilization achieves maximum reactivity per unit mass and can minimize the amount of the metal used, which is very economical.

  • Publication number: 20210273240
    Abstract: Disclosed are a catalyst electrode for a fuel cell, a method for fabricating the catalyst electrode, and a fuel cell including the catalyst electrode. The presence of an ionomer-ionomer support composite in the catalyst electrode prevents the porous structure of the catalyst electrode from collapsing due to oxidation of a carbon support to avoid an increase in resistance to gas diffusion and can stably secure proton channels. The presence of carbon materials with high conductivity is effective in preventing the electrical conductivity of the electrode from deterioration resulting from the use of a metal oxide in the ionomer-ionomer support composite and is also effective in suppressing collapse of the porous structure of the electrode to prevent an increase in resistance to gas diffusion in the electrode. Based on these effects, the fuel cell exhibits excellent performance characteristics and prevents its performance from deteriorating during continuous operation.

  • Publication number: 20210159512
    Abstract: The present disclosure relates to a method for preparing a metal single-atom catalyst for a fuel cell. The method for preparing a metal single-atom catalyst uses a relatively lower amount of chemical substances as compared to the conventional methods and thus is eco-friendly, uses no liquid through the whole process and avoids a need for additional steps for separating and/or washing the catalyst after its synthesis, thereby allowing simplification of the process, and can produce a single-atom catalyst at low cost. In addition, unlike the conventional methods having a limitation in metallic materials, the method can be applied in common regardless of types of metals, and thus is significantly advantageous in that it can be applied widely to obtain various types of metal single-atom catalysts. Further, in the method for preparing a metal single-atom catalyst, metal atoms totally participate in the reaction. Thus, the method can minimize the usage of metal to provide high cost-efficiency.
