Title:
FUEL CELL AND VOLTAGE TAPPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/194361
Kind Code:
A3
Abstract:
A fuel cell having a plurality of contacting regions on flow field plates (10) comprises at least one conductive rubber element (50), which has electrically conductive regions (51) and electrically insulating regions (52) following one another in alternation. The conductive rubber element (50) is disposed at an angle (α) to an orthogonal (O) to the contacting surfaces on the flow field plates (10), the condition B ≥ 3.5 ∙ p ∙ cos(α) - b ∙ sin(α) being satisfied, where B is the width of the contacting surface on the flow field plates (10), b is the width of the electrically conductive regions (51) and electrically insulating regions (52) of the conductive rubber element (50) and p is the grid pitch of the conductive rubber element (50).
