Fuel cell equipment and fuel cell energy system

Abstract

The invention provides fuel cell equipment and a fuel cell energy system. The fuel cell equipment comprises a galvanic pile, a reactant input pipe, a heat exchange pipe and a first heat-conducting part, wherein the reactant input pipe is connected with the galvanic pile to input a reactant; the heat exchange pipe and at least one part of the reactant input pipe are arranged in parallel; a flow channel in the heat exchange pipe is separated from the flow channel in the reactant input pipe through a first partition wall; and the first heat-conducting part is connected to the galvanic pile and the heat exchange pipe to transfer waste heat generated by the galvanic pile to the heat exchange pipe. The heat exchange pipe of the fuel cell equipment is used for carrying out heat exchange with the reactant input pipe while the first heat-conducting part transfers the waste heat generated by the galvanic pile to the heat exchange pipe, so that the heat exchange pipe transfers the waste heat generated by the galvanic pile to the reactant input pipe to keep the temperature of the reactant input pipe and the reactant in the reactant input pipe; the condition that moisture condensation affects smooth transportation of the reactant or causes water logging of the galvanic pile due to an over-low temperature is avoided; and in addition, the fuel cell equipment is low in energy consumption, and plays roles in energy conservation and environmental protection.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to a fuel cell device and a fuel cell energy system. Background technique [0002] A fuel cell is a power generation device that directly converts chemical energy stored in fuel and oxidant into electrical energy. Since it is not limited by the Carnot cycle, its direct power generation efficiency can be as high as more than 45%. It is environmentally friendly, high energy conversion efficiency, Long service life and other characteristics have broad application prospects in the fields of aerospace, submarines, electric vehicles, power stations, mobile devices, and households. Taking the proton exchange membrane fuel cell (PEMFC) as an example, the core power generation module of the battery, the stack, is composed of several single cells in series, and the single cell is composed of membrane electrodes, anode plates and cathode plates (or bipolar plates) to form a sandwich structure. Among...
