Water cell longevity

Seed longevity is a function of fhe interaction of wafer confent, storage temperature and unknown quality characteristics. To develop more predictive models of the rate that seeds deteriorate under extremely cold or dry conditions we have studied how water in these systems behave. We have discovered that there are limited benefits to both temperature and water content in prolonging seed lifespans. These critical conditions may reflecf a change in how water and constituents of cells inferacf. 

Temperature Distribution Along the fuel cell channel, the temperature distribution is directly controlled by the heat transfer boundary conditions. For small fuel cell stacks, with no active coolant flow, the external boundary conditions control the temperature distribution and at low current can be considered as uiriform in temperature. For larger stacks with active cooling, the temperature distribution can be engineered to match the desired humidity profile to control flooding and promote longevity by ehmination of dry- and hot-spot locations. In the in-plane direction, temperature variation exists, with more water accumulation under generally colder lands, as discussed. The temperature distribution in the stack can be fairly...
