45. Is the hydrogen released from HYDRNOL pure enough for fuel cells?
Fuel cells require very pure hydrogen. The specification usually calls for 99.999% purity (so-called 5 nine purity). A further requirement is that compounds that could damage the fuel cell must be at extremely low levels: 4 parts per billion for sulfur, for instance.
Asemblon certifies its hydrogen to meet both of these requirements.
