The waste heat needs to be hot to be of high quality. The waste-heat from a HTPEM fuel cell (~155°C) is therefore by definition of higher quality than waste-heat from a LTPEM fuel cell (~70°C).

The waste-heat needs to be concentrated in a usable directional stream. In Serenergy's case more than 90% of the waste-heat leaves the fuel cell system through the exhaust-pipe and is therefore easy to utilize.

Since the waste-heat in Serenergy's fuel cell systems is of high quality and is conatined in a usable directional stream it is easy, cheap and simple to recover some, or most, of the waste-heat using air-to-air or air-to-liquid heat exchangers.
