摘要： A fuel reformer includes a housing. A mixing portion is provided in the housing, the mixing portion being a space for mixing fuel supplied from the outside with an EGR gas. A reforming catalyst portion is provided on a side opposite the mixing portion and is configured to reform the mixed fuel and the EGR gas in the mixing portion. A first heater is disposed around an outer periphery of the housing surrounding the mixing portion. A second heater is disposed around an outer periphery of the housing surrounding the reforming catalyst portion. The first and second heaters are configured to transmit thermal energy to the fuel reformer.

摘要： Disclosed is a method of manufacturing an electrocatalyst. The method may include forming a metal layer on a substrate, treating a substrate of the metal layer, and forming a catalyst layer on the metal layer by applying potential to an aqueous deposition solution including a nickel precursor, a copper precursor, a phosphorus precursor, and an additive, in which a molar ratio of the nickel precursor to the copper precursor may be greater than about 49:1. Accordingly, the present invention has an advantage in that the process of manufacturing the electrocatalyst may be simplified.
