Fuel cells having microfibrous hollow membrane separators with fiber-reinforced ion exchange polymeric membrane walls. Bi-directional low capacitance TVS protection circuit consists of two pairs of TVS diodes, and LC PIN or NIP diodes,. Absorption axes of the first and second polarizing plates are orthogonal to each other, and an optical axis of a liquid crystal in the IPS panel and the absorption axis are parallel with each other.
