1. An assembling method for assembling a bipolar plate for a fuel cell, comprising an anode plate and a cathode plate, which are superposable, wherein it applies a bonding method comprising the following steps:
providing a slow-setting adhesive and a quick-setting adhesive wherein the slow-setting adhesive is configured to have a slower setting than a quick-setting of the quick-setting adhesive,
depositing on the anode plate and/or the cathode plate an adhesive of a first type, from among the slow-setting adhesive or the quick-setting adhesive,
depositing on the anode plate and/or the cathode plate an adhesive of a second type, different from the first type, among the slow-setting adhesive or the quick-setting adhesive,
bringing the two plates into contact,
pressing and
setting of the slow-setting adhesive
to assemble the anode plate with the cathode plate.
 
4. An assembling method for assembling a fuel cell, comprising a stack periodically alternating a bipolar plate and a membrane plate, the bipolar plates all being oriented in the same direction, wherein it applies a bonding method comprising the following steps:
providing a slow-setting adhesive and a quick-setting adhesive wherein the slow-setting adhesive is configured to have a slower setting than a quick-setting of the quick-setting adhesive,
depositing on the bipolar plate and/or the membrane plate an adhesive of a first type, from among the slow-setting adhesive or the quick-setting adhesive,
depositing on the bipolar plate and/or the membrane plate an adhesive of a second type, different from the first type, among the slow-setting adhesive or the quick-setting adhesive,
bringing the two plates into contact,
pressing and
setting of the slow-setting adhesive
to assemble the bipolar plate with the membrane plate.
