The catalyst includes a nanoparticle comprising a metal or metal alloy. The nanoparticle is selected to improve catalytic performance in the electrochemical device. The catalyst further includes an electron-conductive nano-zeolitic framework encasing the nanoparticle. The nano-zeolitic framework includes a hollow three-dimensional framework defining a catalyst surface, an internal cavity in which the nanoparticle is disposed, and a plurality of pores extending through the nano-zeolitic framework.

Abstract: A fuel cell system includes a hotbox configured to house a fuel cell stack, the fuel cell stack including a temperature sensor configured to detect temperature inside the fuel cell stack. The system includes a first tank including a first valve and configured to store methanol. The system includes a second tank including a second valve and configured to store water. The system includes a controller communicatively coupled to receive signals from the temperature sensor and control each of the first valve and the second valve. The controller is configured to set a dosing rate of methanol, based on a temperature of the fuel cells stack, to a predefined dosing rate and initiate operating at least one of the first valve and the second valve to deliver a mixture of methanol and water at the predefined dosing rate to prevent re-oxidation of an anode of the fuel cell stack.

Abstract: The present disclosure provides a membrane electrode assembly (MEA) with high-efficiency water and heat management for a direct ethanol fuel cell (DEFC), and a fabrication method therefor, and belongs to the technical field of fuel cells. In the MEA for a DEFC in the present disclosure, a cathode catalyst layer is designed to be convex and ordered and an anode catalyst layer is designed to be concave and ordered, which is conducive to the timely discharge of the generated heat. The MEA for a DEFC can be fabricated by gradually fabricating each layer of the MEA on an inner surface and an outer surface of a proton-exchange membrane (PEM) or by step-by-step dip coating on an anode support tube. The present disclosure can effectively improve the working capacity of the cell.

Abstract: A reformer assembly includes a vortex tube receiving heated fuel mixed with steam. A catalyst coats the inner wall of the main tube of the vortex tube and a hydrogen-permeable tube is positioned in the middle of the main tube coaxially with the main tube. With this structure the vortex tube outputs primarily Hydrogen from one end and Carbon-based constituents from the other end. In some embodiments a second vortex tube receives the Carbon output of the first vortex tube to establish a water gas shift reactor, producing Hydrogen from the Carbon output of the first vortex tube.
