Description
Technical Field
The invention relates to a fuel cell, in particular to an integrated fuel cell with compact structure and higher efficiency.
Background
An electrochemical fuel cell is a device that is capable of converting hydrogen fuel and an oxidant into electrical energy and reaction products. The inner core component of the device is a Membrane Electrode (MEA), which is composed of a proton exchange Membrane and two porous conductive materials sandwiched between two surfaces of the Membrane, such as carbon paper. The membrane contains a uniform and finely dispersed catalyst, such as a platinum metal catalyst, for initiating an electrochemical reaction at the interface between the membrane and the carbon paper. The electrons generated in the electrochemical reaction process can be led out by conductive objects at two sides of the membrane electrode through an external circuit to form a current loop.
At the anode end of the membrane electrode, fuel can permeate through a porous diffusion material (carbon paper) and undergo electrochemical reaction on the surface of a catalyst to lose electrons to form positive ions, and the positive ions can pass through a proton exchange membrane through migration to reach the cathode end at the other end of the membrane electrode. At the cathode end of the membrane electrode, a gas containing an oxidant (e.g., oxygen), such as air, forms negative ions by permeating through a porous diffusion material (carbon paper) and electrochemically reacting on the surface of the catalyst to give electrons. The anions formed at the cathode end react with the positive ions transferred from the anode end to form reaction products.
In a pem fuel cell using hydrogen as the fuel and oxygen-containing air as the oxidant (or pure oxygen as the oxidant), the catalytic electrochemical reaction of the fuel hydrogen in the anode region produces hydrogen cations (or protons). The proton exchange membrane assists the migration of positive hydrogen ions from the anode region to the cathode region. In addition, the proton exchange membrane separates the hydrogen-containing fuel gas stream from the oxygen-containing gas stream so that they do not mix with each other to cause explosive reactions.
In the cathoderegion, oxygen gains electrons on the catalyst surface, forming negative ions, which react with the hydrogen positive ions transported from the anode region to produce water as a reaction product. In a proton exchange membrane fuel cell using hydrogen, air (oxygen), the anode reaction and the cathode reaction can be expressed by the following equations:
and (3) anode reaction:
and (3) cathode reaction:
in a typical pem fuel cell, a Membrane Electrode (MEA) is generally placed between two conductive plates, and the surface of each guiding plate in contact with the MEA is die-cast, stamped, or mechanically milled to form at least one or more guiding grooves. The guide electrode plates can be plates made of metal materials or plates made of graphite materials. The diversion pore canals and the diversion grooves on the diversion electrode plates respectively guide the fuel and the oxidant into the anode area and the cathode area on two sides of the membrane electrode. In the structure of a single proton exchange membrane fuel cell, only one membrane electrode is arranged, and a flow guide polar plate of anode fuel and a flow guide polar plate of cathode oxidant are respectively arranged on two sides of the membrane electrode. The flow guide polar plates are used as a current flow collection mother plate and mechanical supports at two sides of the membrane electrode, and flow guide grooves on the flow guide polar plates are also used as channels for fuel and oxidant to enter the surfaces of the anode and the cathode and as channels for taking away water generated in the operation process of the fuel cell.
In order to increase the total power of the whole proton exchange membrane fuel cell, two or more single cells can be connected in series to form a battery pack in a straight-stacked manner or connected in a flat-laid manner to form a battery pack. In the direct-stacking and serial-type battery pack, two surfaces of one polar plate can be provided with flow guide grooves, wherein one surface can be used as an anode flow guide surface of one membrane electrode, and the other surface can be used as a cathode flow guide surface of another adjacent membrane electrode, and the polar plate is called a bipolar plate. A series of cells are connected together in a manner to form a battery pack. The battery pack is generally fastened together into one body by a front end plate, a rear end plate and a tie rod.
A typical battery pack generally includes: (1) the fuel (such as hydrogen, methanol or hydrogen-rich gas obtained by reforming methanol, natural gas and gasoline) and the oxidant (mainly oxygen or air) are uniformly distributed in the diversion trenches of the anode surface and the cathode surface; (2) cooling fluid (such as water) is uniformly distributed into cooling channels in each battery pack through an inlet and an outlet of the cooling fluid and a flow guide channel, and heat generated by electrochemical exothermic reaction of hydrogen and oxygen in the fuel cell is absorbed and taken out of the battery pack for heat dissipation; (3) the outlets of the fuel gas and the oxidant gas and the corresponding flow guide channels can carry out liquid and vapor water generated in the fuel cell when the fuel gas and the oxidant gas are discharged. Typically, all fuel, oxidant, and cooling fluid inlets and outlets are provided in one or both end plates of the fuel cell stack.
The proton exchange membrane fuel cell can be used as a power system of vehicles such as vehicles and ships, and can also be used as a mobile or fixed power station.
Proton exchange membrane fuel cells are generally assembled by several single cells in series or parallel to form a fuel cell stack.
As shown in fig. 1-3, fig. 1 is a schematic structural diagram of a single-cell flow guide plate of a fuel cell stack, fig. 2 is a schematic structural diagram of a single-cell three-in-one electrode of the fuel cell stack, and fig. 3 is a schematic structural diagram of the fuel cell stack. The flow guide polar plate and three-in-one electrode of single cell of fuel cell are equipped with six (or less than six) flow guide holes, these six flow guide holes are respectively fuel (hydrogen) inlet, fuel (hydrogen) outlet, oxidant (air) inlet, oxidant (air) outlet, cooling fluid (water) inlet and cooling fluid (water) outlet. After the guide polar plates of a plurality of fuel battery monocells and a three-in-one electrode are assembled into a fuel battery stack, six guide channels in the fuel battery stack are formed by the guide polar plates and six guide holes in the three-in-one electrode, oxidant (air) is uniformly introduced into the six guide channels respectively, the oxidant (air) is uniformly distributed on the guide polar plates of each monocell through the guide channels and reacts on the electrode, product water and excessive oxidant (air) generated by the reaction are uniformly collected into an oxidant (air) discharge channel in the fuel battery stack, other channels are respectively used for introducing fuel (hydrogen) into the channels, the fuel (hydrogen) is collected into the discharge channel, cooling fluid (water) is introduced into the channels, and the cooling fluid (water) is collected into the discharge channel.
As shown in fig. 4 to 5, in the current engineering design of the fuel cell stack, the six flow channels are generally directly collected on the same panel at the front end of the fuel cell stack (fig. 4), and the six flow channels are also collected on two panels at the front end and the rear end of the fuel cell stack, for example, three flow channelsare collected on each panel at the front end and the rear end (fig. 5). The six channels of the fuel cell stack generated by the former design technology are integrated on the same panel, and the six channels of the fuel cell stack generated by the latter design technology are integrated on the front panel and the rear panel.
The inlets and outlets of all oxidant (air), fuel (hydrogen) and cooling fluid (water) on a plurality of (more than 2) fuel cell stacks are uniformly integrated to form six channels. The oxidant (air), fuel (hydrogen) and cooling fluid (water) in the six channels are uniformly distributed to each fuel cell stack, and the oxidant (air), fuel (hydrogen) and cooling fluid in each fuel cell stack are discharged and uniformly converged on the large channels from which the oxidant (air), fuel (hydrogen) and cooling fluid (water) are discharged in the six channels, so that the operating conditions of a plurality of fuel cell stacks are uniform and identical. This integration technique of several fuel cell stacks is generally achieved by the following method: the fuel cell stack is arranged into a fuel cell stack array, six fluid pipelines are respectively arranged beside the array, for example, a large pipeline for oxidant (air) branches off a plurality of uniform thin branch pipes, each thin branch pipe is connected with the oxidant (air) in each fuel cell stack, and the other five pipelines also branch off a plurality of uniform thin branch pipes and are connected with the same corresponding fluid in each fuel cell stack.
The currently widely implemented fuel cell flow guide channel integrated panel design and multiple fuel cell stack integration technology have the following defects:
(1) the six diversion channels are directly converged on the same panel at the front end of the fuel cell stack, the diversion channels in the fuel cell stack are correspondingly long, fluid resistance is easily generated, large pressure loss is caused, and then fluid is unevenly distributed in each single cell in the fuel cell stack, and performance difference of each single cell is caused.
(2) The design makes the inlet and outlet of the diversion channel at the front and back ends respectively to force the pipeline connection to be incapable of being concentrated together and dispersed at the two ends, when the fuel cell is used as a vehicle-mounted or ship-mounted power system, the pipeline dispersion is not beneficial to the arrangement of the cell.
(3) The technical defect is that the design and installation are very difficult because of too many pipelines, leakage is easy to generate and the crowding problem is very prominent.
