Can improve air -cooled fuel cell stack of battery performance

This openly belongs to air -cooled fuel cell field, and concretely relates to can improve air -cooled fuel cell stack of battery performance piles including fuel cell and personally experiences sth. Part of the body, the top of the fuel cell stack body for the air outlet, still is provided with an arc air guide plate for air inlet just is provided with draught fan, bottom under the fuel cell stackbody, arc air guide plate is greater than fuel cell stack at the ascending projected area of axle and personally experiences sth. Part of the body at the ascending projected area of axle, and arc airguide plate's indent faces the body to fuel cell stack. This openly can and form hot -blast encirclement ring on every side in fuel cell stack body bottom to improve fuel cell stack body exit temperature, reduce the difference in temperature simultaneously, reduce the heat that the heat radiation heat dissipation was taken away, reduce the demand to the air quantity, reduce the probability that the battery performance rec
