Description
Technical Field
The invention relates to the field of fuel cells, in particular to a flow field plate of a fuel cell and the fuel cell.
Background
The hydrogen-air fuel cell is a clean energy technology capable of directly converting chemical energy of fuel and oxidant into electric energy, and has the advantages of simple structure, high efficiency, environmental protection, low noise, wide working temperature range and the like. The fuel cell bipolar plate guides and distributes fuel and oxidant gas to an active area for chemical reaction on one hand, and also exhausts redundant water in the cell on the other hand, so as to prevent the cell from being flooded by water, and the bipolar plate also plays a role in collecting current. The flow channel pattern of the bipolar plate determines the flow conditions of the reactants and products within the flow channel, thereby affecting the uniform distribution of the reactants throughout the electrode. Therefore, the reasonable flow field plate structure can greatly improve the performance of the fuel cell.
Common fuel cell flow channels include parallel flow channels, serpentine flow channels, mesh flow channels, and the like. Although the pressure loss of the parallel flow channels is small, the uneven gas distribution is easily caused; although the serpentine flow channel has strong drainage capacity, the flow channel is too long, so that the pressure drop of reaction gas is too large, and the phenomena of insufficient supply of the reaction gas and flooding are easily caused at the rear section of the flow channel. Although the mass transfer process is enhanced by the mesh-shaped flow channels, the drainage capacity is poor and the flow uniformity is not ideal due to the low gas flow velocity in the flow channels.
The utility model with the patent number of CN98108958.5 provides a novel flow channel structure, and the characteristic of this kind of structure is the cross-sectional area that reduces the runner gradually to make the velocity of flow of gas in the runner improve gradually to gas outlet along gas inlet, strengthen the diffusion effect of reaction gas to the catalysis layer. However, this configuration does not compromise the problem of water droplet collection in the disposal flow path and is difficult to machine. Thus, existing flow field plates remain to be improved.
