Description
Technical Field
The invention relates to a fuel cell, in particular to an assembly frame suitable for large-scale rapid assembly and test of a fuel cell stack.
Background
An electrochemical fuel cell is a device capable of converting hydrogen 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 cathode region, 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 guide plate in contact with the MEA is die-cast, stamped, or mechanically milled to form at least one or more channels. The flow guide polar plates can be polar plates made of metal materials or polar plates made of graphite materials. The fluid pore channels and the diversion trenches on the diversion polar 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 present, and a guide plate of anode fuel and a guide plate of cathode oxidant are respectively arranged on two sides of the membrane electrode. The guide plates are used as current collector plates and mechanical supports at two sides of the membrane electrode, and the guide grooves on the guide 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) the inlet and outlet of cooling fluid (such as water) and the flow guide channel uniformly distribute the cooling fluid into the cooling channels in each battery pack, and the heat generated by the 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.
Fig. 1 shows a flow guide plate in a single cell of a conventional fuel cell, which includes an air inlet 1a, a water inlet 2a, a hydrogen inlet 3a, a flow channel 4a, an air outlet 5a, a water outlet 6a, and a hydrogen outlet 7 a; fig. 2 is a three-in-one membrane electrode in a single cell of a conventional fuel cell, which includes an air inlet 1a, a water inlet 2a, an electrode active region 8a, an air outlet 5a, a water outlet 6a, and a hydrogen outlet 7 a; fig. 3 shows a conventional fuel cell stack, which includes a fuel cell stack 9a, collector motherboards 10a, 10b, end plates 11a, 11b, metal tie rods 12a, and nuts 13 a.
The existing fuel cell stack is generally formed by assembling a plurality of monocells (the monocells are composed of a flow guide polar plate and a three-in-one membrane electrode), a flow collecting mother plate, a front end plate and a rear end plate, wherein a plurality of pull rods are arranged on the front end plate and the rear end plate, and the front end plate and the rear end plate are compressed into the fuel cell stack by using fasteners generally; the fastener tie-rod plus screw method is the usual fastening method.
The fuel cell stack must be sufficiently compressed by the fasteners, but must be uniformly compressed within a suitable pressure range to ensure safe and efficient operation of the fuel cell stack.
When the fuel cell is produced on a large scale, a large number of single cells (the single cells are generally composed of a flow guide polar plate and a three-in-one membrane electrode), a positive current collecting conductive mother plate, a negative current collecting conductive mother plate, a front end plate and a rear end plate are assembled on a large scale to form a fuel cell stack, and the fuel cell stack is subjected to operation test. The method mainly comprises the steps of carrying out operation test on the fuel cell stack successfully assembled for the first time according to product design technical indexes, and mainly detecting the current and the voltage output by the fuel cell stack, even the working voltage of each single cell in the fuel cell stack under the operation parameters of different pressures, flow rates, temperatures and the like.
Generally, each unit cell or other component of a successfully assembled fuel cell stack may not meet the specifications of the product design, so the entire fuel cell stack must be disassembled again, replaced with a unit cell or component of inferior quality, and reassembled until the operational test requirements are passed.
At present, the conventional fuel cell stack which is fastened and assembled by using the tie rods and the fasteners is very unfavorable for repeated assembly, and great obstacles are brought to large-scale fuel cell stack assembly and test.
1. The requirement for fastening and assembling the tie rods of the fuel cell stack is particularly high, and it must be achieved that each area on the front end plate and the rear end plate of the whole fuel cell stack is basically and uniformly subjected to fastening force, which is very difficult, and practical operation often causes that a certain area on the front end plate and the rear end plate of the whole fuel cell stack is subjected to relatively small fastening force, and a certain areais subjected to relatively large fastening force, so that certain areas on the fuel cell pole plates are subjected to insufficient pressing force, so that the contact resistance of the electrodes and the guide pole plates is too large, and the pressing force of certain areas is too large, so that the pole plates are deformed or cracked, or the electrodes are damaged.
2. When the fuel cell stack is tightly assembled by the pull rod, when the fuel cell expands or contracts due to heat, the front end plate and the rear end plate of the fuel cell stack are stressed differently, and the pole plates or the electrodes can be damaged in serious cases.
3. Each time such a fuel cell stack is assembled by tightening the tie rods, a lot of time is required, and large-scale rapid assembly and testing cannot be achieved.
