Micro-Channel Heat Exchanger for Metal Hydride Hydrogen Storage

Summary

Researchers at Purdue University have developed a unique micro-channel heat exchanger for solid-state hydrogen storage. The internal micro-channel design optimizes both powder/pellet contact area for increased heat transfer and hydride powder/pellet capacity. This highly efficient heat exchanger provides the necessary cooling power to meet the Department of Energy's fill time target of less than five minutes. This is the only design to achieve this target. No other metal hydride storage system have been demonstrated to cross the five minute fill time mark. In fact, published values range from 10 to as high as 100 minutes.
