|GEI Releases High-Temperature APU|
GEI's patented high temperature fuel cell stack design has flow field channel designs optimized for reformed fuels and incorporates a robust manifold design scalable from 2kw-10kw.
This allows a single design for a wide of range of power requirements without re-occurring engineering design cost and provides the scalability necessary for large volume commercialization to reduce manufacturing cost.
High-Temperature PEM (HT-PEM) Fuel Cells (160C) provide a balance between the operating characteristics and cost of LT-PEM fuel cells (80C), and the fuel diversity and fuel impurity tolerance of high temperature solid oxide fuel cells. The primary advantage of HT-PEM fuel cells is their tolerance of CO fuel impurities e.g. < 5% by volume, as compared to 0.02% by volume for LT-PEM fuel cells. As such, low temperature steam reforming (550C-600C) of logistic fuels does not require separate and expensive preferential oxidation reactors and membrane purifiers that increase cost and complexity. For cost sensitive applications requiring logistic fuels, HT-PEM fuel cells significantly reduce fuel processing equipment cost, weight, and size, while providing high-grade heat for combined heat and power (CHP) applications, and increased system efficiencies.
