Research On Intergration System Of Hydrogen Generation And Supplement For Flexible Fuel Cell System

With the popularization of the application of portable devices,people’s requirements for the energy system of these portable electronic devices are also improving,and higher requirements have been put forward in terms of their portability,environmental friendly and duration.For these constantly generating new demands,traditional micro energy system couldn’t satisfy people’s needs any more,and the proton exchange membrane fuel cell,a kind of high efficiency energy systems,is a promising substitution for them.Because it hass high energy conversion efficiency,environment friendly without pollution during its work.And hydrogen from hydrolysis of aluminum based composite material is expected to be a source of hydrogen for portable fuel cell due to it’s a kind of solid hydrogen storage material,and hydrolysis reaction is violent at room temperature,the hydrogen production is high and the hydrogen is suitable for fuel cell.The main content of this paper is a series of experiments and explorations on the application of hydrogen from hydrolysis of aluminum based composite material in flexible fuel cells.In terms of flexible proton exchange membrane fuel cell.In the integration system of hydrogen generation and supplement for the fuel cell some work were did including made of aluminium matrix composites by aerosol,test of the hydrolysis reaction of aluminium matrix composites by drainage method in different water bath temperature and reactant ratio,and according to the data in hydrogen production and time relationship summed up two different application environment of the reactant,and be able to get hydrogen production,and sums up the two based on the experimental data of concrete under different scenarios using scheme.The hydrogen produced by hydrolyzing aluminum matrix composites at the same flow rate was compared with pure hydrogen supplied to the same fuel cell system.For the part of integrated energy system,including the preparation of flexible proton exchange membrane fuel cell,including the selection of catalyst,gas diffusion layer,proton exchange membrane and other materials,and the realization of the process.Three kinds of flow channel are designed and made for proton exchange membrane fuel cell,according to the commonly used several kinds of design form the corresponding gas flow channel,and the use of flexible proton exchange membrane fuel cell under different flow performance was tested,then we get the most suitable flow channel and the corresponding hydrogen flow rate needed for the fuel cell.According to the obtained fuel cell system,the fluid based simulation is carried out to obtain the gas distribution in the flow channel.Then compare the performance of the fuel cell powered with the same rate supplement of hydrogen from hydrogen gas and hydrolysis of aluminum based composite material.We can get that fuel cell powered by hydrogen from hydrolysis of aluminum based composite material peforms better.
