Abstract

The invention discloses a multi-purpose PTC water heater for fuel cells, which comprises a shell body. A liquid flow channel is arranged in the inner cavity of the shell body, and the liquid flow channel is of an S-shaped structure. One end of the liquid flow channel is an inlet end, and the other end is an outlet end. The outer wall of the liquid flow channel is coated with a heat insulating material layer. PTC heaters are installed on the outer walls of the inlet end and the outlet end respectively. The multi-purpose PTC water heater for fuel cells of the invention has the advantages of simple structure principle, high heating efficiency and good efficiency, has a double heat insulating effect, can achieve the purpose of fuel cell heating and heat insulating, has a good energy saving effect, and can prolong the service life of fuel cells.

Description

technical field [0001] The invention relates to the technical field of fuel cell heating, in particular to a fuel cell multipurpose PTC water heater. Background technique [0002] The principle of a fuel cell is an electrochemical device whose composition is the same as that of a general battery. Its single cell is composed of positive and negative electrodes (the negative electrode is the fuel electrode and the positive electrode is the oxidant electrode) and the electrolyte. The difference is that the active material of the general battery is stored inside the battery, thus limiting the battery capacity. The positive and negative electrodes of the fuel cell itself do not contain active materials, but are just catalytic conversion components. Therefore, a fuel cell is a veritable energy conversion machine that converts chemical energy into electrical energy. When the battery is working, fuel and oxidant are supplied from outside to react. In principle, as long as the re...
