Aus dem 10-K Report 2018:
In addition to research and development performed under research contracts, we also fund our own research and development projects including extending module life, increasing the power output of our modules and reducing the cost of our products. Current initiatives include increasing the net power output of the fuel cell stacks to 375 kW from 350 kW, and extending the stack life to seven years from five-year life modules produced in fiscal 2017. The Company’s seven-year module design will enter production in fiscal 2018. Greater power output and improved longevity are expected to lead to improved gross margin profitability on a per-unit basis for each power plant sold and improved profitability of service contracts, which will support expanding gross margins for the Company.
