Abstract
Two novel fuel cell designs attempt to improve efficiency and reduce the balance of plant weight by implementing a square hole through the center of the bipolar plates. Air is forced through the square hole for the purpose of oxygen delivery, water removal, and stack cooling. This study demonstrates, for the two novel designs, a more even temperature distribution and hot spots away from the center of the bipolar plates. This reduces the number and size of components required to effectively run the system, thus reducing the weight of the balance of plant. Four simulations are presented in this paper, with inlet gases and initial cell temperature set to 333Â K. The maximum temperature for case 1 without cooling is 347.97Â K, case 1 with water cooling is 335.29Â K, case 2 with forced air cooling is 339.42Â K, and case 3 with forced air cooling is 335.13Â K.
