Question: Exact solution of coupled system

restart:

Eq2 := diff(T(y), y, y)+(diff(sigma(y), y))*(diff(T(y), y))+(diff(T(y), y))^2+(exp(-y)

+exp(y))^2 = 0;

Eq3 := diff(sigma(y), y, y)+(diff(T(y), y, y))= 0;

bcs2:=T(h1)=0,T(h2)=1,sigma(h1)=0,sigma(h2)=1;

dsolve({Eq2,Eq3,bcs2});

This give me nothing. Please help me out.
