Description
Technical field
The present invention relates to fuel cell field, refer in particular to a kind of small-sized direct methanol fuel battery stack modularization assembly and activation method thereof.
Background technology:
Directly using methyl alcohol is that the JPL (institute is tested in U.S. jet-propulsion) of early 1990s NASA (American National aviation and space travel office) and the researcher of University of Southern California propose as the conception of the direct methanol fuel cell (DMFC) of Proton Exchange Membrane Fuel Cells (PEMFC) fuel.Because methyl alcohol is liquid (64.51 ℃ of boiling points) at normal temperatures, the hydrogen more used than other fuel cells, methane or carbon monoxide have the energy density (combustion heat 726.83kJ/mol) of better storge quality and Geng Gao.In addition, methyl alcohol also is very cheap industrial products, can obtain from oil, natural gas and coal easily.Its working temperature and pressure are all very low, thereby simple in structure, and fail safe might as well.During work, a battery release of carbon dioxide and steam do not contain other poisonous and harmful compositions.In all kinds of fuel cells, these characteristics that direct methanol fuel cell has become it development potentiality most in the portable power supplies field.
The traditional stack formula structure that Proton Exchange Membrane Fuel Cells (FEMFC) is adopted is difficult to realize miniaturization, and feed needs extra power consumption.Under compact power slimming, light-weighted requirement, direct methanol fuel cell (the Motorola Inc. (2000) that a kind of novel unipolar plate structure occurred, U.S. Pat 6127058), it is in one plane to realize series connection between the different membrane electrode assemblies by electric power connector.At present, the passive type air-breathing Direct Methanol Fuel Cell substantially all is to adopt this structure.
As everyone knows, fuel cell is the system of a complexity, except the membrane electrode assembly that electrochemical reaction takes place, and the control system of also will respond thing and product, power-supply management system or the like.Usually then an act as a fuel basic structural unit of battery system of the membrane electrode assembly basic structural unit of battery pile that acts as a fuel, battery pile.And the kind and the size of current battery heap all are to be decided according to actual conditions by the developer, and wherein the specification of membrane electrode assembly is also had nothing in common with each other, and is unfavorable for so forming very much a unified standard.In addition, for a lot of membrane electrode assembly cell stack assembled, in case wherein certain is out of joint, detect or more new capital be very difficult.
Summary of the invention:
