  • Publication number: 20240079609
    Abstract: A separator for a fuel cell includes a reaction region, a pair of manifold regions on opposite sides of the reaction region and through which a plurality of manifolds pass, configured to introduce or discharge reaction gas or coolant, and a pair of diffusion regions between the reaction region and the manifold regions, configured to diffuse a flow of the reaction gas or coolant. Diffusion ribs in the diffusion regions are spaced apart from each other along the manifolds. The diffusion ribs may be spaced apart such that diffusion flow fields formed between the diffusion ribs have different cross-sectional areas for respective regions at ends adjacent to the manifold regions.

  • Publication number: 20120092370
    Abstract: An apparatus to provide AR includes a marker recognition unit to recognize objects in reality information, an amalgamation determining unit to determine whether the objects are amalgamated, an amalgamation processing unit to determine an attribute of each of the recognized objects and to generate an amalgamated object based on the determined attributes, and an object processing unit to map the amalgamated object to the reality information and to display the mapped amalgamated object. A method for amalgamating objects in AR includes recognizing objects in reality information, determining whether the objects are amalgamated, determining an attribute of each of the recognized objects, generating an amalgamated object based on the determined attribute, mapping the amalgamated object to the reality information, and displaying the mapped amalgamated object.
