The present invention relates to a method of determining the net water drag coefficient in a fuel cell. The apparatus also includes a bulbing assembly which is releasably engagable with the cable bolt. The supporting portion extends from the rear surface and is configured for supporting the digital picture frame on a supporting surface. These recesses result in protrusions formed on the articles, which protrusions must then be removed in a machining operation. Movement of the support disk enables selective engagement of the resistance source. The top section is arranged at least partially above the storage space in the closed state of the top, and the covering member is connected to the rear top section by at least one connecting member.
