SOFC and Coal Syngas

• Syngas Product of coal gasification
• Typical Compositions 30 H2, 26 H2O, 23 CO,
  21 CO2.
• Intentionally
  control the water concentration to
• prevent carbon
  deposition (coking) on the anode surface.
• Contaminants H2S, HCl, PH3, AsH3, Hg, Sb, Zn,
  Cd, Se, HCl etc. They
• may react and destroy
  the cell anode.

of Power Sources 163 (2007) 986996

• In coal syngas PH3 concentration is typically
  1-10 ppm.
