(1) electrode effective area utilance is low, general＜80%;
(2) guide plate is heavier or area is bigger, and effectively the water conservancy diversion area utilization is also lower, generally is less than 80%.
Summary of the invention
For overcoming above-mentioned defective, the object of the invention provides a kind of electrode effective area utilance height, little, the lightweight ionic membrane fuel cell with high power density of volume.
The technical solution adopted for the present invention to solve the technical problems is: the amberplex both sides also comprise airtight interlayer, the gaseous diffusion carrier, metal lead wire, described membrane electrode and the stack of airtight interlayer also are rolled into one or more layers roll type, described gaseous diffusion carrier is located at the both sides of membrane electrode, described metal lead wire is located on the gaseous diffusion carrier, constitutes the ion-exchange membrane fuel cell that a roll type has high power density thus.The every volume of ion-exchange membrane fuel cell that above-mentioned roll type has high power density is interrupted for one section, constitutes a monocell, and each monocell is connected in series or parallel.
As a further improvement on the present invention, described battery also comprises airtight interlayer, gaseous diffusion carrier, metal lead wire, membrane electrode and interlayer are rolled into one or more layers roll type, be provided with the two membranes electrode between the interlayer of this roll type and the interlayer, described gaseous diffusion carrier is provided with between membrane electrode and the membrane electrode and between membrane electrode and the interlayer, described metal lead wire is located on the gaseous diffusion carrier.Constitute the ion-exchange membrane fuel cell that a roll type has high power density thus.The every volume of ion-exchange membrane fuel cell that described roll type has high power density is interrupted for one section, constitutes a monocell, and each monocell is connected in series or parallel.Described catalyst is a platinum catalyst.Described gaseous diffusion carrier adopts flexible metal silk screen or carbon fibre material.
Compared with prior art, the present invention carries out diverse design with the core component in the fuel cell, change the plane superimposed type into several layers or one deck roll type, do not need guide plate, thereby solve two defectives in the above flat fuel cell, improved the power density of fuel cell greatly.
